摘　　要：提出了一种以三维循环对称有限元模型计算制动过程中制动盘温度场和应力场的方法。讨论了温度场和应力场有限元分析时载荷和边界条件的确定 ,以及变材料常数的处理。利用大型有限元软件 ANSYS建立了制动盘的三维对称循环有限元模型 ,对一种制动盘进行了计算和分析 。This paper proposes a method to calculate the transient temperature field and stress field of a working brake disc with 3 dimensional cycle symmetric model. The necessary loads and the boundary conditions in the finite element analysis of temperature field and stress field are discussed and the problem of material non linearity is solved. The 3 dimensional brake plate model is established and by means of large scale finite element software ANSYS a brake plate calculation example is illustrated. Eventually, the calculation results are analyzed in detail and compared also with the experiment data.
