This gives an indoor-based simulation tool which is important for vehicle testing;.<br>This reduces the cost significantly with accurate results, especially when designing a new<br>suspension system. The aim of the current work was to build a new quarter-vehicle test rig<br>with expandable capabilities for diverse design objectives, also may be used for academic<br>purposes. The control objective was achieved by using dynamic characteristics of the<br>electrohydraulic (EH) damper to suppress the oscillation of the sprung mass due to road<br>irregularities. The test rig was constructed using a Genesis G80 (2016) suspension system.<br>Finally, the simulation results demonstrated that the proposed controller used be able to<br>efficiently regulate the chassis vertical oscillation under these irregularities. The experimental<br>results for the quarter-car model showed good results between experimental and simulated<br>results, where the proportion of conformity about 95%</span> </p> ER -
