中文摘要：

将制动中的辐射换热等效为对流换热，建立汽车鼓式双领蹄制动器三雏热弹耦合模型。考虑制动摩擦力矩的影响，对多次连续制动工况下的制动鼓瞬态温度场、应力场、变形场进行有限元数值模拟，获得制动鼓的内外表面的温度、热应力及热机耦合强度变化规律。

英文摘要：

The three-dimensional thermo-elastic coupling finite element model （FEM） of a double-leading-shoe brake was established by equaling radiation heat transfer to convective heat transfer. The transient temperature field, stress field and deformation field of the brake were numerically simulated several times under the continuous braking condition and by considering the braking friction torque. The transient temperature, heat stress and thermo- elastic coupling strength change on the internal and external surfaces of the brake were obtained.
