摘要
由于地铁相邻站点之间的距离较短且地铁列车的行驶速度较快,所以为了快速有效地制动列车,地铁列车会在传统电机制动系统的基础上加入空气制动系统来弥补列车制动力的不足。文章以空气制动辅助方式作为研究对象,具体分析电空混合制动原理以及两种辅助方式的工作原理,通过ABAQUS有限元仿真软件对车轮踏面进行仿真分析,对比两种辅助方式对车轮踏面温度变化的影响程度。
Because of the short distance between the adjacent stations and the fast running speed of the subway train, in order to brake the train quickly and effectively, the subway train will add the air brake system on the basis of the traditional motor braking system to make up for the deficiency of the train braking force. The article takes the air brake assist method as the research object, specifically analyzes the principle of electro-air hybrid braking and the working principle of the two assist methods, simulates and analyzes the wheel tread through the ABAQUS finite element simulation software, and compare the influence of the two auxiliary methods on the temperature change of the wheel tread.
