Performance Optimization Design of a Bus Engine Mounting System
SHI Tianhua
Abstract: To effectively enhance the vibration isolation performance, this paper determines the optimal stiffness of the vibration-damping cushions and the mounting angles of the mounting bracket by the decoupling simulation of the mounting system. The vibration isolation performances of the mounting and the vehicle are improved by increasing the dynamic stiffness of the mounting bracket.
