Optimization Design of Powertrain Mounting System of a Bus
摘要
Abstract
According to the parameters of a 6902 type passenger car suspension system measurement,we establish dynamic model of the powertrain mounting system of 6 degrees of freedom.By using the energy decoupling method and NAGA-II optimization algorithm,first based on orthogonal test method,we has the sensitivity analysis of system stiffness parameters for powertrain mounting,and taking the 6 directions of coupling of powertrain mount system as the design goal,taking three main stiffness parameters of 6 directions as design variables,the powertrain mounting system was optimized.The experimental results show that after optimization,the suspension system can effectively improve the anisotropy of the decoupling rate and achieve the reasonable allocation,the natural frequency,which improves the isolation performance of the mounting system,and improves the ride comfort of the car.关键词
