Increase of compliance of shock absorbers with cut shells

The problem of the protection of equipment and personnel from harmful vibrations is among the most burning issues of current machine building. The aim of the paper is to model prefabricated structures of shelled shock absorbers with the basic component as the cut cylindrical shell with low-compressible elastomeric filler. The conducted analysis showed that as a result of dry friction of the filler against the shell, the contact pressure unevenly distributes along the cylinder, and that is why extensive increase in the length of the shell is not a productive measure to increase the compliance of the damper. We have offered an aggregated shock absorber in the form of a set of consecutively installed shorter cut shells with filler. We have formulated and solved the optimization problem to determine the length of the link of the multi-section shock absorber with fixed sizes of the intermediate piston. We have described the hysteresis characteristics of the multilink shell-shaped absorbers under cyclical loading.
