摘　　要：为考虑刹车盘接触对之间的摩擦特性对刹车过程的影响,采用CATIA建立某型机轮刹车盘的三维实体模型,经简化后获得其有限元模型;利用ANSYS/LS-DYNA显示动力学分析软件,对刹车盘进行瞬态动力学分析,得到了动盘表面节点轴向振动曲线和刹车过程中刹车片的应力分布情况。In order to study the effect of the friction characteristics of the brake disc in the process of braking. In this paper, a three-dimensional solid model of an aircraft wheel brake disk is established by CATIA, then its finite element model is crea-ted by simplifying the geometry model; Transient dynamics analysis is carried out on the brake disk by using ANSYS / LS-DYNA(explicit dynamic analysis software). In the end, the node axial vibration curve and the distribution of stress of the brake during the process of brake are got.
