为了分析受横风作用的车辆动态性能,建立了基于静态分析模型的动态分析模型,通过横向动载荷实车试验,验证了动态分析模拟程序的有效性。在比较了静态分析方法和动态分析方法差异的同时,验证了横风频率对车辆动态性能的影响,提高了临界倾覆风速的评价精度。
In order to analyze the dynamic performance of a vehicle subjected to crosswind, a dynamic analysis model based on the static analysis model was established. The effectiveness of the dynamic analysis and simulation program was verified through a real dynamic test of a transverse dynamic load vehicle. While comparing the difference between the static analysis method and the dynamic analysis method, the influence of the transverse wind frequency on the vehicle dynamic performance is verified, and the evaluation precision of the critical tipping wind velocity is improved.
