Loading device for oncoming dynamic loading

P. A Vlasov · Tractors and Agricultural Machinery · 2014

Methods of running and testing of parts, units and aggregates under load in case of transferring required drive torques through them are considered. The method of loading by oncoming drive torques using inertial loaders is theoretically substantiated.

Controlling Dynamic Torsion Loading

Benjamin Claus · Figshare · 2019

Two new Kolsky bar techniques were developed to address a lack of capability in existing torsion Kolsky bar experiments. The side-impact torsion Kolsky bar provides for controllable duration, amplitude, and shape of the incident torsion wave, allowing for more ideal conditions during dynamic torsion experiments. The technique provides an ideal platform to study dynamic friction as well as dynamic shear of a material. The technique makes use of soft pulse shapers to convert longitudinal loading into torsional loading. The technique also brought forth a secondary technique to allow combined dynamic compression and dynamic torsion for soft materials. The combined loading was applied to study both shear properties and the friction behavior of aparticle composite, which was imaged using x-ray phase contrast imaging. The same composite was studied with different surface conditions on the side-impact torsion Kolsky bar to discover the differences in behavior brought about by the choice of manufacturing method. The composite showed different friction behavior to metallicmaterials, and exhibited much more shear deformation during the experiment. The composite was also prone to surface evolution, leading to complex friction behavior.

Dynamic compression loading summary.

Alexander R. A. Szojka (7324973), Colleen N. Moore (10284674), Yan Liang (139654) et al. · Figshare · 2021

<p>A) Tissues were compressed from 0–10% strain at 1 Hz for one hour (3600 cycles). B & C) Representative force vs. time plots for tissues (loading day 10) that had medium supplemented with or without TGF-β3, respectively. D) Representative force vs. strain plots for two cycles near the end of a loading period (loading day 10). The water only group was included to show the magnitude of any frictional forces using a comparable platen stroke. E) Sample heights were measured on each loading day and were used to calculate displacements for application of the 10% strain waveform. F & G) Peak and equilibrium moduli calculated using the force changes across the first and last cycles, respectively, of each loading period for each donor. Only significant (p<0.05) linear correlations were included.</p>

Dynamic Loading of Bridges

Rob Heywood, W. Milnor Roberts, G Boully · Transportation Research Record Journal of the Transportation Research Board · 2001

Management of the aging bridge infrastructure is demanding an increased understanding of all aspects of the performance of existing bridges. Loading models are an important consideration in the risk assessment of a structure. Quantifying the actual in-service dynamic response of a structure can make a significant difference in terms of keeping a bridge in service. Code-recommended allowances for dynamic effects range between 20 and 40 percent for major elements. Higher values are sometimes recommended for local effects. It is well understood that parameters including the unevenness of the road profile, the potential of frequency matching between heavy vehicles and the bridge, vehicle speed, and heavy-vehicle load levels all contribute to the dynamic response of a bridge to a single-vehicle event. Multiple vehicles increase the complexity even further. Recent new editions of bridge codes around the world tend to have diversified the methods and allowances for dynamic effects. These methods are compared, and then they are compared with a database of experimental responses measured in a range of structures in Australia and New Zealand during recent years. The results clearly illustrate the importance of each of the above parameters and that very large dynamic responses can be achieved, particularly in short-span structures.

Repeated and Dynamic loading

FIORAVANTE, Vincenzo, MUZZI F. · Institutional Research Information System University of Ferrara (University of Ferrara) · 1991

The response of deep foundations to repeated dynamic loading has been a subject of considerable interest in recent years
\nin relation to the seismic design of important structures such as nucIear power plants, offshore structures and vibrating
\nmachines, etc,
\nIn spite of significant efforts on the part of theoretical and experimental researchers and the avai!ability of powerful
\ncomputers, because ofthe complex interaction effects in the superstructure-foundation-soi! system, and - more importantly
\n- the inelastic nature of the soil behaviour, exact solutions to the problem are stilI not available.
\nIn current practice the engineer is necessarily faced with simplified, uncoupled, iterative procedures valid for specific
\ncases; the choice of a methodology associated with the definition of relevant soil properties is stilI fundamentaly empirica!.
\nThe review ancl discussion of possible theoretical approaches are here mainly oriented toward their applicability and
\nshortcomings in light of the more recent experimental and theoretical developments.
\nBasic aspects related to geotechnical investigations and the cletennination of soil properties are pointecl out, as well as
\nthe mai n factors that govern important phenomena such as clegraclation of soi! characteristics due to cycIic loacling ancl
\nclepenclence of stiffness ancl strength on rate of loading.
\nAdvantages associated with the use centrifuge ancl full scale moclels both for research ancl for practical applications are
\ninclicatecl, especially in presence ofvery complex nonlinear boundary problems such as those representecl by large pile group
\nfoundations.
