Abstract [en]

Some years ago, the Society of Experimental Mechanics’ (SEM’s) Technical Division (TD) on Dynamic Substructuring recognized a need for a simpler yet challenging benchmark structure for experimental-numerical substructuring exercises. That structure should replace the modified version of an Ampair 600 wind turbine as the common test object within the TD. Representatives from several research institutes formed a group that defined several desirable properties for the new benchmark structure. The outcome is a frame structure together with a differnt plates. Together, they can represent various structures such as automotive frames, wing-fuselage structures and building floors. The frame is made as a one-piece structure with many 10/32 tapped holes that can be used to attach other components, sensors or excitation devices.Sandia National Labs has manufactured the benchmark structure’s components, an aluminum frame together with two aluminum rectangular wings. An exercise/challenge has been formulated. The components have been shipped to the ones that have shown interest in participating in the exercise. The idea of the exercise is to compare different strategies to tackle an experimental substructuring task, containing both decoupling and coupling, thereby learning from each other.In the exercise, the participants start with an assembly built up by the frame and the thinner of the rectangular wings. That wing should then be numerically decoupled from the fuselage. To that numerical representation of the fuselage, the thicker wing should be coupled numerically. These decoupling and coupling operations render in a numerical representation of the thicker wing attached to the fuselage; a representation which output is compared with test data stemming from the real structure counterpart.Here, virtual points are used in the decoupling and coupling operations. Four attachment points, e.g., four screws, are used. In addition, washers between the fuselage and the wings are used in the connections. The purpose is to avoid too challenging non-linearities to start with. The Component Mode Synthesis (CMS), technique is used.

Abstract [en]

Research focus on experimental dynamic substructuring has grown in recent years in bothacademic and industrial interests. Methods to couple and decouple in the modal domain, i.e., usingComponent Mode Synthesis (CMS), the frequency domain, i.e., Frequency Based Substructuring(FBS), and the state-space domain have been developed to high pedigree. In addition, the use ofvirtual point transformations in substructuring exercises has opened new opportunities for thedefinition of substructuring constraints. The Society of Experimental Mechanics’ (SEM’s)Technical Division on Dynamic Substructuring recognized a need for a simple, yet challengingbenchmark structure for experimental-analytical substructuring collaborations as compared toprevious benchmark structures [1] [2] [3]. A team with members from many research institutes setout from several desirable properties and a unit-frame structure was designed as a benchmark forcurrent collaborative efforts detailed in [4]. The benchmark structure is built up by a frame withthreaded inserts that is bolted to plates of varying thickness and materials. When assembled thisstructure can span a diverse application space of substructuring techniques including automotiveframes, wing-fuselage structures, and structural frames and floors. The frame is made as a onepiecestructure; it consists of four units cells and includes 10/32 tapped holes that can be used toattach other components. In addition, 10/32 tapped holes are made on the side of the frame toattach impedance heads or force transducers.Substructuring is often used to connect test and finite element (FE) based subassembly models.Each model can play to its strengths with FE models containing high fidelity spatial density andexperimental models capturing difficult to model pieces of an assembly, i.e., joint mechanics. Inthis work the benchmark structure’s components, an aluminum frame together with a rectangularwing manufactured by Sandia National Labs, are combined with swept steel wings manufacturedby Linnaeus University. The study combines a test-based model of the assembled frame andrectangular wing with FE models representing wing subcomponents. The rectangular wing isnumerically decoupled from the fuselage by the use of an FE model representing the wing and theswept wing is then numerically coupled to the frame using an FE model. The modal substructuringpredictions are then compared with results from measurements on the assembly.

Abstract [en]

Wind-induced dynamic excitation is a governing design action determining size and shape of modern Tall Timber Buildings (TTBs). The wind actions generate dynamic loading, causing discomfort or annoyance for occupants due to the perceived horizontal sway, i.e. vibration serviceability problem. Although some TTBs have been instrumented and measured to estimate their key dynamic properties (eigenfrequencies, mode shapes and damping), no systematic evaluation of dynamic performance pertinent to wind loading had been performed for the new and evolving construction technologies used in TTBs. The DynaTTB project, funded by the ForestValue research program, mixed on site measurements on existing buildings excited by mass inertia shakers (forced vibration) and/or the wind loads (ambient vibration), for identification of the structural system, with laboratory identification of building elements mechanical features, coupled with numerical modelling of timber structures. The goal is to identify and quantify the causes of vibration energy dissipation in modern TTBs and provide key elements to finite element models. This paper presents an overview of the results of the project and the proposed Guidelines for design of TTBs in relation to their dynamic properties.

Abstract [en]

Forced vibration tests have been conducted on the seven-storey timber building Eken in Mariestad inSweden. The main objective is to estimate the building’s dynamic properties from test data. The eigenfrequencies, modeshapes and their scaling are useful to calibrate numerical models. However, the most important outcomes are the estimatesof the modal damping values. The reason is that the damping impacts the acceleration, and thus the serviceability of thebuilding, and at the same time, it is very hard to model damping. So, during the design phase, one must rely on previoustest data (of which very few exist for taller timber buildings) or rule of thumbs. It is therefore important to gain knowledgeabout the damping for timber buildings in order to enable good designs of future and taller timber buildings. The test datashows that the modal damping is roughly equal to 2% of the critical viscous ones for the eigenmodes extracted. The testcampaign on Eken is made as a part of the project Dyna-TTB in which vibrational tests have been performed on eighthigh-rise timber buildings, in Europe, of which Eken is one.

Abstract [en]

Within the project Dyna-TTB, vibrational tests have been conducted on eight high-rise timber buildings, in Europe. A main objective of the project is to gain knowledge about damping in timber buildings to assist in predicting the accelerations, at the top of a building, due to wind-induced vibrations.One of the buildings is Eken (the oak) in Mariestad in Sweden. That building is seven stories tall, thus questionable as a tall timber building, yet an interesting test object. The building structure is made up of glue laminated timber beams and columns stabilized with glulam trusses.Forced vibration were conducted on Eken with the aim to estimate the building’s dynamic properties from test data. Estimates of the eigenfrequencies, mode shapes and their scalings are useful both in the calculations of wind-induced vibrations and to calibrate numerical models. However, the most important outcome is estimates of the modal damping values. The damping impacts the acceleration, and thus the serviceability of the building, and at the same time, it is very hard to model damping. So, during the design phase, one must rely on previous test data (of which very few exist for taller timber buildings) and rule of thumbs. It is therefore important to gain knowledge about the damping for timber buildings in order to enable good designs of future and taller timber buildings.

Abstract [en]

The limitations in performance of band-pass filters to accurately process rapid decaying signals in lower frequency bands is an obstacle for some measurements within building acoustics. For instance, it would be beneficial to be able to accurately measure reverberation times down to the 20 Hz one-third octave band for impact sound in timber buildings.

Here, it is tested whether calculations with FFT with small incremental steps may be a way to achieve discrete frequency time signals with faster performance than traditional band-pass filters. The tests show that incremental FFT gives accurate estimations of the reverberation time corresponding down to 0.1 seconds at 20 Hz with a spectral resolution of 2 Hz. Using the one-third octave limits it is possible to form approximate one-third octave band results. It is seen that accurate estimations of reverberation time are achievable for BT ≥ 0.5 (T = 0.1 seconds for the 20 Hz one-third octave band) and possibly even lower, if the dynamic range in the interrupted noise signal is sufficient. The higher one-third octave results show to work as well. A disadvantage with the method is that during short reverberation times (0.1 seconds) there is a severe spectral leakage to the side bands. Also, the method requires higher dynamic range decay signals compared to band-pass filtered signals. If a one-third octave resolution is requested, a dynamic range of 50 dB or greater is preferable. With a coarse resolution of e.g., 10 Hz and having no averaging into one-third octave bands, it is possible to measure short reverberation times (0.1 s) with signals having close to the same dynamic range used in classical band-pass filtered reverberation time measurements.

Abstract [en]

Measurements of reverberation time is often used to obtain information about sound absorption of rooms within building acoustics. A limitation of the common method used today is the performance of band-pass filters to process rapidly decaying signals in the low frequency range. This occurs when the reverberation time (T) and bandwidth (B) product is less than 16. This is a limitation infor instance multi-story timber buildings where low frequency range, below 50 Hz is of interest for impact sound performance. Here, an alternative method is tested. Using incremental short time steps between each FFT calculation creates “moving average” signals, one for each frequency spectral line. A disadvantage is that the methodrequires a high dynamic range of the interrupted noisesignals, which increases with frequency resolution. Here itis tested to fit in the frequency resolution to the one-thirdoctave band frequency limits with as small errors as possible. It is shown that the dynamic range can be decreased a bit compared to a previously presented version. Two disadvantages with just one spectral line for each third octave band is that the signals are less stable and to produce the different frequency resolutions for each one-third octave requires more calculations.

Abstract [en]

There is an increasing need for an effective monitoring strategy for the performance and condition of Down The Hole drilling. To achieve that, it is important to gain knowledge in the physics involved in Down The Hole drilling processes.A logical way to gain such understanding is to develop simulation models that are capable to represent the process. That requires physical understanding and thus, it is an iterative process. To capture the physics, it is essential to couple the axial impact, and the subsequent axial motion, with the rotation of the drill. The indentation into the rock due to impact and the subsequent resistance against rotation will couple the rotation to the axial motion and vice versa. The scenario is complicated due to the non-linear nature in the contacts and the varying stiffness of the rock.This paper presents a methodology that can be used to couple the axial and rotational motions of the DTH drills and explores the pros and cons of such a 3D simulation model.Keywords: DTH, 3D simulation, Condition monitoring

Abstract [en]

In a Finnish-Swedish consortium project, a large amount of sound insulation tests wasconducted for several intermediate floors in laboratory conditions to serve variousscientific research questions. The dataset contains 30 wooden and 8 concreteconstructions which are commonly used between apartments in multistorey buildings.Impact sound insulation was determined according to ISO 10140-3 standard usingboth tapping machine and rubber ball as standard sound sources. Airborne soundinsulation was determined according to the ISO 10140-2 standard. The data arespecial since they have a broad frequency range: 20-5000 Hz. Data are reported in1/3-octave frequency bands and the single-number values of ISO 717-1 and ISO 717-2are also reported. Detailed construction drawings are available for all reportedconstructions. The data are highly valuable for research, education, and developmentpurposes since all data were obtained in the same laboratory (Turku University ofApplied Sciences, Turku, Finland), and all the constructions were built by the same installation team.

Abstract [en]

Wooden floors usually have worse impact sound insulation (ISI) at low frequencies than concrete floors having the same rating level. Rating level is usually expressed by single-number quantities (SNQs), such as weighted impact sound pressure level Ln,w. Psychoacoustic research among wooden floors is very limited although a controlled laboratory experiment is the strongest method to point out the most adequate SNQs to be declared for the floors. The purpose of our study was to determine how four standardized SNQs of ISO 717-2, Ln,w, Ln,w +CI, Ln,w +CI,50, and LiA,Fmax,V,T, and a recently proposed SNQ, Ln,w +CI,25, are associated with the annoyance of natural impact sounds transmitted through wooden floors. Fifteen floors were built in the laboratory based either on cross laminated timber (heavy) or open box wood (light) slabs. Different coverings and suspended ceilings were applied on these slabs. The ISI was tested within 25-3150 Hz using both tapping machine and rubber ball. Thereafter, five natural impact sounds were recorded for each floor: rubber ball drops, steel ball drops, walking, jumping, and chair pushing. Fifty-two people rated the annoyance of these 75 recorded natural impact sounds in psychophysics laboratory. Annoyance was best associated with Ln,w for all the five impact sound types. That is, measurement of ISI within 100-3150 Hz is sufficient from subjective point of view. All four SNQs based on tapping machine explained annoyance better than the SNQ based on rubber ball. Our results can significantly guide the future research, development, and regulations of wooden floors.
