摘　　要：为了提高大型运输车行驶中的平顺性,提出将动力吸振器应用于整车振动控制方法。以9自由度整车-路面耦合模型为基础,建立含有动力吸振器的13自由度整车-路耦合动力学方程,运用遗传算法对动力吸振器的相关参数进行优化,并对动力吸振器安装位置和车辆不同速度进行数值仿真分析。经过对比分析,结果表明:动力吸振器能够明显改善车辆的平顺性,在轮胎上方效果最好,动力吸振器在车速大时减振效果更明显。In order to improve the driving comfort of large transport vehicles,it is proposed to apply dynamic vibration absorbers to the vehicle vibration control method.Based on the 9-degree-of-freedom vehicle-road coupling model,a 13-degree-of-freedom vehicle-road coupling dynamics equation with dynamic vibration absorber is established,and the relevant parameters of the dynamic vibration absorber are optimized by genetic algorithm,and the installation position of the dynamic vibration absorber and difference speeds are optimized.After comparative analysis,the results show that:the dynamic vibration absorber can significantly improve the ride comfort of the vehicle,and the effect is best above the tire;the dynamic vibration absorber has a more obvious damping effect when the vehicle speed is high.
