Frequency Analysis and Optimization Design of Car Powertrain Mounting System Based on ADAMS

This paper introduced the method that developed model and frequency analyses of powertrain mounting system based on ADAMS (Automatic Dynamic Analysis of Mechanical Systems ). The six vibration frequencies and its corresponding modes were obtained and compared with experimental results. Mount stiffness of the four mounting parts were optimized to use Adams/Insight. The former low decoupling degrees and the new part stiffness were observed to improve the disadvantage and can reduce the vibration transfer.
