Cleat Impact Analysis of a Multi-body Quarter Vehicle System with Finite Element Models

The main purposes of the present work represent a modeling of a multi-body quarter vehicle system and a methodology of a cleat impact simulation. The multi-body quarter vehicle is modeled as a finite element. The nonlinear tire model is a simple 3D solid type. The parts of the quarter vehicle were connected by a joint element. The spring-dashpot joint element was used to consider the effect of the suspension. A transient dynamic analysis was performed to confirm the vibrational result of the cleat impact. The analysis step consists of four parts: tire inflation, stabilization, tire-road interaction, and cleat impact.
