Control and experimental evaluation on a quarter-car test rig

Abstract EN

In this paper a quarter-vehicle full-scale suspension test rig was designed and manufactured, the suspension is considered semi-active as the electrohydraulic (EH) damper used is fully controlled.

This gives an indoor-based simulation tool which is important for vehicle testing; .

This reduces the cost significantly with accurate results, especially when designing a new suspension system.

The aim of the current work was to build a new quarter-vehicle test rig with expandable capabilities for diverse design objectives, also may be used for academic purposes.

The control objective was achieved by using dynamic characteristics of the electrohydraulic (EH) damper to suppress the oscillation of the sprung mass due to road irregularities.

The test rig was constructed using a Genesis G80 (2016) suspension system.

Finally, the simulation results demonstrated that the proposed controller used be able to efficiently regulate the chassis vertical oscillation under these irregularities.

The experimental results for the quarter-car model showed good results between experimental and simulated results, where the proportion of conformity about 95%.
