Abstract
Applying the multi-dynamic theory, a dynamic model of the power-train mounting system of motor vehicles is established. An optimization model for the power-train mounting system is constructed, in which decoupling efficiency of six freedom vibrations is selected as objective function, and the natural frequency distribution of system as constraint condition, the stiffness and installing angles as design variables of optimization. Based on improved particle swarm optimization, as an example, isolation characteristics of a truck power-train mounting system are analyzed. The comparison between the optimal and original design shows that distribution of both the modal kinetic energy and the system natural frequency are more reasonable, that means NVH of the power-train mount system can be improved using the optimal design.
