摘要
Abstract
Engine mounting system is very important for automobile vibration and noise control. In this paper, a 15-DOF vehicle's body and the powertrain mounting system coupled model is established. With the decoupling rate of the torque shaft and the total transferred vibration force as the objective functions, the whole vehicle structure is optimized considering the common driving conditions. The particle swarm optimization (PSO) algorithm is used to optimize the mounting stiffness parameters with the use of the identified excitation forces as the actual force input. The results show that choosing proper stiffness parameters of the mounting system can effectively reduce the transferred vibration force and increase the decoupling rate of the torque shaft so that the comfort of the automobiles can be improved.关键词
