四、承载系统动载荷的频率特性汽车承载系统各部件,在行驶过程中,除了承受静载荷外还承受因振动引起的附加载荷,这就是动载荷。不同零部件所受的动载荷的频率特性是不同的。以下将逐一加以分析。而在频率特性的基础上作动载荷的统计分析方法,已在第一节中作过叙述。1.车体动载与车轮振动的频率特性。所谓车体动载荷,就是在汽车行驶中,悬架系统
Fourth, the bearing system of dynamic load frequency characteristics Car carrying system components, in the driving process, in addition to bear the static load but also because of the additional load caused by vibration, which is dynamic load. Different components subjected to dynamic load frequency characteristics are different. The following will be analyzed one by one. The statistical analysis of the dynamic load on the basis of the frequency characteristics has already been described in the first section. 1. The dynamic characteristics of vehicle body and wheel vibration frequency. The so-called car body dynamic load, that is, in the car, the suspension system
