Abstract
Shock Testing is an essential evaluation criterion to assess the performance of newly designed systems for their dynamic performance. There are various methods to generate a shock pulse for shock testing, like free fall drop test, horizontal impact, kick, and explosion. The primary purpose of this research is to design and characterize the pulse shaper of neoprene rubber for Shock testing of heavy objects. This paper presents an implicit Finite-Element (FE) model of the impact of a test table on a rubber disc. The FE model is used to study the influence of drop height, the mass of the object, and the thickness of the pulse shaper on shock pulse characteristics. Shock tests were also conducted on the test stand, and a comparison of the results from the FE and experimental data is presented in this paper.

Keywords
Drop Test, FEM analysis, Hyperelastic, Neoprene rubber shock pulse.
