Abstract

ABSTRACT The gauge differences of international rail lines have led to the emergence of variable-gauge trains. High-speed variable-gauge trains operating on different lines should meet the dynamic requirements. In order to achieve the above purpose and obtain better dynamic performance, a parameter optimization method for variable suspension systems is proposed. The SIMPACK dynamic model of high-speed variable-gauge trains is established. Six key parameters of the suspension system are chosen, and different suspension parameters are combined using the optimal Latin hypercube. Seven dynamic indices of the vehicle running on three different gauge tracks are solved separately. Weighted SNR is used to perform the multi-objective optimization. The improved CRITIC method is used to solve for the weight coefficients of each index, and find the optimal values of the key suspension parameters. The objective of adjusting the variable suspension parameters of variable-gauge trains is presented. Results from simulation show that the optimized suspension parameters can improve the dynamic performance of the variable-gauge vehicle, especially the derailment coefficient, the wheel load reduction rate, and the axle lateral force. The vehicle can operate with better dynamic performance on both gauge lines by using the designed variable suspension parameters.

基于改进CRITIC方法的变轨距列车变悬架参数优化设计

国际铁路的轨距差异导致了变轨距列车的出现。在不同线路上运行的高速变轨列车应满足动力要求。为了达到上述目的并获得更好的动态性能，提出了一种可变悬架系统的参数优化方法。建立了高速变轨列车的SIMPACK动力学模型。选择了悬架系统的6个关键参数，利用最优拉丁超立方体对不同悬架参数进行组合。分别求解了车辆在三种轨距轨道上运行的七项动态指标。采用加权信噪比进行多目标优化。采用改进的CRITIC方法求解各指标的权重系数，求出悬架关键参数的最优值。提出了变轨距列车变悬架参数的调整目标。仿真结果表明，优化后的悬架参数能显著改善变规车辆的动力学性能，尤其是脱轨系数、轮载减载率和轴侧力。采用所设计的可变悬架参数，可使车辆在两条轨距线上具有较好的动态性能。
