摘　　要：为研究转K2型转向架弹簧两级刚度转换点的刚度非线性对车辆动力学性能的影响,以N17AK型平车为研究对象,利用车辆系统动力学分析软件UM建立了动力学计算模型并进行了分析。仿真结果和线路动力学试验结果都表明,N17AK型平车空车、半重车、重车工况下的各项动力学性能考察指标都在GB/T 5599—1985规定的范围内;N17AK型平车在半重车工况下的各项动力学性能考察指标均没有出现脉冲式的变化,即弹簧刚度转换点对车辆动力学性能不会产生脉冲式的影响。In order to research on the effect of the non-linear stiffness performance of the 2-stage conversion point of Zhuan K2 bogie spring on the vehicle dynamics performance,with N17 AKflat car as the object of research,the dynamics analysis software UM for vehicle systems is used to set up the dynamics calculation model and make the analysis.Both the simulation result and the dynamics test result on line show that all the dynamics performance indexes in the investigation of the empty,semi-loaded and loaded N17 AKflat cars are within the range specified in GB/T5599-1985;there is no pulse type change in any of the dynamics performance indexes in the investigation of the semi-loaded N17 AKflat cars,i.e.,the stiffness conversion point of springs will not have pulse type effect on the vehicle dynamics performance.
