Abstract

Abstract

Wheel-rail profile compatibility has an important influence on the dynamic performance of rail vehicles. The present standard JM₃ wheel profile has a large difference in equivalent conicity when it is matched with different types of rail profiles in China. It has the problem of locomotive swaying caused by too low equivalent conicity when the profile is matched with the grinding rail with large rail cant. To address these issues, the optimization objective of reducing the equivalent conicity dispersion of the wheel profile matched with CN60 and CN60N rail profiles under different rail cants was set. The wheel profile was described by a method combining arcs and straight lines. The JM₃ wheel profile was optimized by utilizing NSGA-II genetic algorithm to improve the lateral position parameters of the two arc centers near the rolling circle. The wheel-rail contact characteristics and the locomotive dynamic simulation of the wheel profile before and after optimization were compared. The results show that when the optimized wheel profile is matched with the rails above, the nominal equivalent conicities at the 3 mm transverse displacement of the wheelset are all about 0.1, which reduces the equivalent conicity dispersion of the original JM₃ wheel profile and improves the adaptability of the wheel profile to different rail profiles and line conditions. At the same time, the locomotive hunting stability, lateral stability, curving performance, and wear performance index of the optimized profile are all improved compared with the original wheel profile. In addition, the phenomenon of low-frequency swaying of locomotives on specific lines is eliminated.
