摘要
汽车悬架及司机座椅动态参数对汽车行驶的平顺性有着重要影响.以八自由度弹簧质量系统作为汽车振动系统的力学模型,用前后四轮路面随机激励作为系统输入,对车厢及司机座椅的输入功率谱进行分析,在此基础上对该模型的悬架及司机座椅动态参数进行优化。
The dynamical parameters of truck seat and suspension system play on important role in the study of vehicle ride quality. A mathematical model with 8degreefreedom is founded for the study of the response in frequency space of the truck seat which is excited by the spectrum of the road. Based on the theoretical analysis the suspension and seat parameters are optimized.
