Analysis of Influence of Polygonal Distribution of High-speed Train Wheels on Wheel-rail Dynamic Characteristics
摘要
Abstract
To research the influence of polygonal distribution of bogie wheels on the dynamic characteristics of wheel rails,establish a rigid-flexible coupling vehicle-track dynamics model based on wheelset flexibility,calculation of wheel-rail dynamic responses caused by polygonalization of different wheels of low-order/high-order bogies,analyze the influence of the polygonal distribution of bogie wheels on the dynamics of wheel rails at different operating speeds,further combine the wheel-rail vertical force limit to formulate the wheel polygon amplitude limit.The results show that in the low-order state,the polygonal distribution of the bogie wheel has a significant influence on the time-domain vibration waveform of the wheel rail creep slip force and the wear power,and the polygons on different sides of the wheel pair will lead to the phase of the wear power being advanced and the integer multiple order harmonics appearing;In the high-order wheel polygon state,the bogie wheel polygon distribution has a significant impact on the vibration amplitude of the wheel-rail dynamic response;The increase of train running speed will aggravate the influence of wheel polygon on the dynamic characteristics of wheel and rail under various working conditions;The polygonal distribution of bogie wheels may have a certain influence on the evolution of wheel polygonal wear.关键词
