Vibration Isolation Performance Simulation and Optimization of Vehicle Powertrain Mounting System
摘要
Abstract
In order to solve the problem of vibration isolation in vehicle powertrain mounting system,the 6 degree of freedom analysis model of powertrain mounting system was established.The key parameters that affected the vibration isolation were analyzed.According to the calculation theory of inherent characteristics of mounting system,dynamics simulation model was established with ADAMS software and inherent characteristics was analyzed with MATLAB to get the system frequency and energy decoupling rate.And then,taking the energy decoupling rate as the goal,the spindle mounting stiffness as the optimization variable,the mounting system was optimized with the optimization function in MATLAB.The results showed that he improved mounting system vibration isolation rate had increased significantly,and the isolation performance had been improved.Adjusting the spindle mounting stiffness can reduce the vibration coupling of the powertrain mounting system,improve the decoupling rate and realize the reasonable configuration of the inherent frequency.关键词
