Abstract

The strut is one of the most important components in a vehicle suspension system; however, it is also one of the most difficult elements to model owing to its highly nonlinear characteristics. In this paper a non-linear gas strut model built in the software package Bathfp is presented. Both analytical and parametric modelling methods were used in the representation of different components in the strut. Simulations at various frequencies showed good agreement with experimental results. A sensitivity analysis of strut performance is presented at the end of the paper. It was found that the damper valve characteristics, the rod diameter, the temperature, and the user-defined polytropic index significantly affect the strut performance.
