盘式制动器的结构场有限元分析

首先探讨盘式制动器在制动过程中的摩擦接触和非线性动力学问题.具体的分析方法包括:摩擦接触算法,非线性有限元方法.按照制动盘与摩擦片的实际几何尺寸,建立了具有速度可变效应的三维瞬态结构应力有限元模型,利用非线性有限元方法,较真实地模拟了制动器的制动过程.通过以上分析得出制动过程的一些结构上的性能变化.将同相同制动条件下的实心盘式制动器和通风盘式制动器对比,得出通风盘式制动器在制动过程中的接触应力,各向位移等.

The finite element analysis of disc brake

At first the method of friction contact and non-linearity dynamics was studied, including friction contact arithmetic and non-linearity element method. The structure stress finite element models with transformable velocity effect which confirm to the true size of the disc and pad are established, on the basis of that, the course of the braking is simulated with the nonlinear finite element model. Some changes of the structure could be got by the course of simulation.Comparing with the solution of the solid disc brake and ventilation disk brake, and get the contact stress and the displacement of the ventilation disk brake?
