Numerical simulation and measurement of car strut under shock vibration

Abstract

This article focuses on the analysis of the properties of the car strut used to capture the engine torque reaction generated during fast acceleration. There is described the methodology of measuring the parameters needed to assess the force effect and also a simulation of the properties of a redesigned strut using the finite element method. The simulation confirmed the correctness of the design and also showed that very small asymmetry of cross section cause significant reducing of the load capacity of the strut and its easy damage.
