车轮多边形对轮轨静态匹配的影响
Influence of Wheel Polygonalization on Static Matching of Wheel and Rail
摘要
Abstract
The influence of wheel polygonalization on the static matching of wheel and rail is analyzed. Assuming that the radius varies periodically around the wheel and considering the variation of the lateral wear of the wheel, a spatial model for the polygonal wheel is established. Since the trace line method is not suitable for polygonal wheels, the minimum distance between the wheel and rail is searched in the spatial wheel model to obtain the contact position and geometric parameters. The normal contact stress and the creep stress are calculated and the influence of the polygonal wheel on the static contact force of wheel and rail is analyzed by Hertz contact theory and Polach creep force model. The calculation results show that the influence of When lateral wear is considered, phase position of the polygonal wheel on the static matching between wheel and rail is negligible. Circumferential wear can cause periodic changes of wheel-rail contact patch and normal stress and the influence degree increases with increasing of the order.关键词
