In this research, the investigated ACS is shown in Figure 1. The vibration isolation performance of CVIS is optimized to improve the camper comfort by proposing an optimization procedure based on EDM. The optimization method based on energy decoupling rate (EDR) of CVIS is proposed to improve the vibration and noise level of camper. Then, an operational vibration test and modal identification test are performed to troubleshoot the vibration and noise level in the camper. Next, based on the energy decoupling method, a genetic algorithm is adopted to optimize the stiffness and EDR of the CVIS, and the vibration isolation element is redesigned as a large-damping pure rubber structure. After that, the strength and stiffness of the vibration isolation rubber element is verified by finite element simulation; finally, operational vibration and noise tests are performed in a camper to verify the effectiveness of the optimization.
