摘　　要：采用数值模拟的方法研究鼓式制动器的温降过程,结合ANSYS对制动鼓的温度场进行有限元分析,并利用台架试验验证有限元模型的准确性;找出温降的规律及其影响因素,提高温度降低的速度,使积留在制动器的热量减少,从而避免热衰退现象,并为长大下坡道路的建设提供理论依据。The process of temperature droping of drum brakes is studyed with the method of numerical simulation .The temperature of the finite element model is analysised with ANSYS, and verified by bench test.To improve the speed of the temperature droping,the role and its impact factors is found to avoid heat recession, and the study provides a theoretical method for the construction of the downhill road.
