The temperature and stress field of friction disks was researched using ABAQUS when matching with three different friction block distribution while the disk structures were the same.The distribution and change of friction disc temperature field and thermal stress field caused by friction block distribution differences were analyzed under friction speed of 50 km/h.The results indicate that,under the same friction block shape as well as the same frictional contact area, the increased friction block number leads to homogenization of friction energy distribution,so the contact between blocks and disks gets homogenized serving to a decreased contact pressure.Consequently,the peak temperature of the friction disk and the friction block is reduced,the temperature fluctuation along with the direction of friction disk thickness is mini-mized,the axial displacement of the friction block is decreased.Under certain friction conditions,the change of brake block number has no obvious influence on the surface stress of friction disk.%利用ABAQUS有限元软件，对3种不同分布方式的摩擦块与相同结构摩擦盘匹配摩擦时的温度场和应力场进行研究，分析摩擦速度为50 km／h的条件下，摩擦块分布方式对摩擦盘的温度场和热应力场的变化及分布的影响。结果表明：在摩擦块形状和摩擦副总接触面积相同的情况下，摩擦块数量增加可使摩擦能量分布均匀化，摩擦块与摩擦面接触变均匀，接触压力减小，起到降低摩擦盘和摩擦块峰值温度的作用；同时摩擦盘沿厚度方向的温度波动程度降低，摩擦块的轴向位移减小；摩擦条件一定时，摩擦盘的表面应力不随摩擦块数量的变化而变化。
