中文摘要：

在考虑具有可变效应的移动热源影响、制动盘与片的弹性影响以及界面摩擦热流影响等的耦合作用下，建立了一个三维瞬态盘式制动器热-结构耦合模型，利用大型有限元软件ANSYS的非线性多场耦合分析方法，分别数值模拟了不同状态下的制动器摩擦接触界面上的压力场分布情况.发现制动接触压力并非均匀分布，而是与制动盘和片的变形、摩擦力以及摩擦热-结构耦合有关.

英文摘要：

A three-dimensional thermal-structural coupling model is estabished, which considers the combined influences of moving heat source, elasticity of disc and pad, and heat flow coupling. By using the ANSYS software, the contact pressure distribution on the contact interface of the disc bake is calculated under three different loads. Numerical results show that the baking contact pressure distribution is nonuniform and dependent on many factors, such as the distortion of the disc and the pad, the friction force and the thermal-structural coupling load.
