This paper aimed to study the behavior of a body (dummy) that was in race car event frontal collision with wall order see what loads were acting on dummy. Based complex model, equipped two safety system seat belts and shock absorption system, dummy obtained following car–dummy assembly. The accelerations at different points dummy’s force appeared determined. Gibbs–Appell method used assess resp...

Abstract During the current global pandemic, when family or household has been considered most basic unit of quarantine, role domestic worker – someone who by definition crosses threshold and enters space home became problematised quickly. These workers’ ‘outsider’ status transgressing boundaries not just physical space, but often also race, immigration status, class meant that some workers wer...

In this work, a preliminary numerical assessment on the application of an additive manufactured hybrid metal/composite shock absorber panels to military seat ejection system, has been carried out. The innovative character concept investigated is that absorbing system thickness only 6 mm and composed pyramid-shaped lattice core that, due its small size, can be achieved by manufacturing. mechanic...

Ca ii λλ3934, 3969 absorbers, which are likely to be a subset of damped Lyman α systems, are the most dusty quasar absorbers known, with an order of magnitude more extinction in E(B−V) than other absorption systems. There is also evidence that Ca ii absorbers trace galaxies with more ongoing star-formation than the average quasar absorber. Despite this, relatively little is known in detail abou...

Bicycle configuration is not as large as those of motorcycles or automobiles, while it indeed composes a complicated dynamic system. People’s requirements on comfortability, controllability and safety grow higher as the research and development technologies improve. The shock absorber affects the vehicle suspension performances enormously. The absorber takes the vibration energy and releases it...

Novel pollutant control equipment, which were called integrated pollutant control equipment, consisted of bag filters and activated carbon (AC) absorbers. The AC absorbers were put forward to absorb the additional pollutants between the old and new emission standards to satisfy Chinese emission standards. The absorbers could be fixed (mobile) bed, annular column, or fluidized bed. The numerical...

Numerical optimisations were conducted to reduce the noise levels inside the payload bay of a rocket by using vibration and acoustic absorbers attached to the fairing walls. The vibration absorbers act in both translational and rotational axes. The acoustic absorbers were modelled as simplified Helmholtz resonators. A Finite Element model of the vibro-acoustic system was created in ANSYS and th...
