Optimization of Vehicle Powertrain Mounting System Based on Adams/View

Abstract:

In order to solve the vibration problem of diesel engine powertrain assembly at its idle state, a six degree-of-freedom dynamics model of the powertrain mounting system is established and a optimization based on Adams/View is applied to simulation and analysis on the powertrain mounting system with energy decoupling method. The results show that the optimized repositioning mounts installation position can effectively improve decoupling rate in main vibration directions of mounting system, proving that the energy decoupling method has good effect on greatly improving the system’s vibration isolation efficiency.
