有限元法在计算摩擦片表面压力方面的应用

Application of finite element methodin calculating pressure of brake shoe

应用有限元法，并结合摩擦理论，建立了计算在动滑动摩擦和极限摩擦条件下的数学模型，从而计算出摩擦片表面各点的径向作用力．并以鼓式双向自增力式制动器的次领蹄为研究对象，进行了分析计算．并探讨了摩擦片表面各点作用力的分布趋势．

A mathematical model in condition of friction is established by means of using finite element method and theory of friction.Radial application force on friction lining has been calculated.An example is calculated about second leading shoe of two leading shoe brake,and the tendency that pressure is dispersed on the friction lining is studied.
