针对中国交通车辆状况以及车辆对路面的作用特点,提出车辆代表轴型——单轴与双联轴,对两种代表轴型分别建立双自由和三自由度车载振动模型,并求解了车载振动模型的稳态解,编制了相关模拟车载动态振动作用的计算程序,进行计算分析,并提出最大附加动荷载的概念来表征车辆荷载振动特性,得出了最大附加动荷载与路面不平整度波长与幅度、车辆速度、车辆载重及系统固有频率等多个参数的关系。
According to the characteristics of traffic vehicles in China and the effect of vehicles on the road surface, vehicle representative shaft types - single shaft and double shaft are proposed. The two free and three degrees of freedom vehicle vibration models are established respectively for the two representative shaft types and the vehicle vibration The steady-state solution of the model is established and the calculation program of the dynamic vibration of the vehicle is simulated. The concept of maximum additional dynamic load is proposed to characterize the vehicle vibration characteristics. The maximum additional dynamic load and the roughness of the road surface And amplitude, vehicle speed, vehicle load and system natural frequency and other parameters of the relationship.
