摘要

为准确分析轨道车辆电制动过程中，制动电阻片表面温度场、流场和压力场，考虑了温度对冷却空气热物理性能的影响，建立了制动电阻片的分析模型。分析结果表明，CFD仿真可为制动电阻设计提供指导。

Abstract

In order to analyze the distribution of surface temperature, velocity and pressure field on the brake resistance chip in the process of rail vehicle’s resistance brake, simulation model of brake resistance chips was established by considering the influence of the temperature on thermal physical property parameters of the air. The results showed that CFD simulation was useful for the design of brake resistor.
