Simulation and Analysis of Quarter Car Model for Low Cost Suspension Test Rig

This paper focuses on a low-cost simulation of a control device that automates the operation of an existing suspension test rig. The rig has a few limitations: it must be manually controlled, the load applied

cannot be specified, and the deflection must be manually measured. A suspension setup can't be checked for different road profiles, either. The proposed control system in this paper effectively automates the process of suspension spring load testing at a cost that is comparable to that of a fully automated test rig on the market, while also expanding the scope of its capabilities. SIMSCAPE was used to map simulation models of both the actual test rig and the updated test rig control system. On both rigs, the results of evaluating suspension components were simulated, and the resulting graphs were compared.
