摘　　要：依据传热学理论和鼓式制动器的结构特点,分析了鼓式制动器的生热和散热过程,并用有限元法建立了制动鼓瞬态温度场数值模拟计算模型。以EQ1092货车后轮鼓式制动器为研究对象,运用ANSYS软件对其制动鼓在持续制动工况下的温升过程进行了数值模拟计算,得出了制动鼓的温度场的三维分布状况,分析了瞬态温度场的变化情况。经过试验验证,计算结果与实测值误差在20%以内。Based on the theory of heat transfer and the constitution of drum brake, this paper analyzes the process of heat＇s creating and dissipating of drum brake, and builds the finite-element numerical simulation model of temperature. Taking the rear drum brake of EQ1092 as the object, sofrware ANSYS is used to simulate the temperature rising process of braking drum in the continuous braking conditions. The three-dimension temperature distribution of braking drum is obtained, and the characteristics of transient thermal field is analyzed. It is proved that the result of the calculation has an error of 20% compared with the test value. 7 figs, 7 refs.
