在研究轨道车辆轮重减载率动态特征的基础上 ,研制了基于一通用车辆垂向模型的计算机仿真程序 ,实现了车辆在不同的固定线路输入下准静态轮重减载率的仿真。利用该程序计算了车辆通过缓和曲线和三角坑时的准静态轮重减载的变化规律 ,并分析了一系悬挂参数对车辆准静态轮重减载率的影响
On the basis of studying the dynamic characteristics of the rolling stock decelerating rate of rail vehicles, a computer simulation program based on a vertical model of a common vehicle was developed, which realizes the simulation of the quasi-static loading weight of vehicles under different fixed line inputs. The program was used to calculate the variation of quasi-static wheel load deloading when the vehicle passed the curve and the triangular pit, and the influence of the first suspension parameters on the para-static wheel load reduction rate
