Design of an Experiment to Identify the Frequency-Dependent Mechanical Properties of Rubbers

Abstract

This diploma thesis work is a part of wheel damper development and is based mainly on the proposal of a piece of metal for measurement of dynamic damping properties. The objective is to create a modal analysis based on the idea of the piece that is currently used by the company, and in addition to them, to propose some other form or model that is more viable and meaningful to be implemented in wheel damper system development. The FEM modal analysis of proposed dimension and mass variants is performed and based on the results the most promising candidates are chosen for dynamic parameters verification, which is done by FEM frequency response analysis. The obtained results are used to assess the dynamic properties of chosen candidates to the dynamic ability of the shaker LDS V650, which is expected for dynamic testing.
