Analysis of the Impact and Mechanical Properties of a Damper Made of Hyperelastic Material

Abstract

The analysis of mechanical properties in the proposed model of the vibration damping element through the use of a layer of hyperelastic material was presented in the paper. The aim of the study was to analyse the behaviour of the structure under the influence of external forcing forces with the use of hyperelastic materials, which are characterized by high compressive fatigue strength. The model in its construction assumes the use of rubber as a material that acts as a vibration damper. The results presented in the paper include the stress-strain relationship and the vibration analyses. The paper contains the conclusions of the comparative analysis in relation to the reference model. The studies were performed using the finite element method using the ANSYS program. Mesh elements were adopted as 3D solid elements, adapted to the model, and properly densified in the places of contact of individual layers in the model. The Mooney-Rivlin material model, in order to analyze the middle layers, was adopted in the work.
