| 摘 要： | 针对快速重载货物列车转向架基础制动方式,对踏面制动热流密度和对流换热系数进行推导和应用,重点分析车轮旋转周期内闸瓦摩擦生热和对流换热交替变化规律,建立了全新的车轮制动过程瞬态温度场三维有限元模型.在摩擦制动动力试验台上进行了制动试验并对模型进行了验证,结果表明该模型能比较完整地反映实际工况.利用该模型进行仿真计算,可以了解各种要素对踏面制动过程的影响,为发展快速重载货物列车的制动方式和制动技术提供了比较可信的理论分析.

| Abstract: | Based on the key parameters derivation of the heat flux density and thermal convection or transfer coefficient on tread-braking mode of fast-heavy-load wagon bogie,one distinctive three-dimensional finite element model of the transient temperature field in wheel braking process was developed to reveal a number of characteristics about the brake heat absorption and transmission in one wheel rotating cycle,and was confirmed through the friction brake power-test-bed for the tread-braking temperature verificati... |
