摘　　要：针对25T型客车用某型制动盘在运用过程中出现的散热筋裂纹故障,文章从故障散热筋在制动盘上的位置出发,对散热筋结构、受力状况及断口失效等方面进行分析,确定故障的形成机理,并从散热筋结构设计及成型工艺角度提出优化措施。优化后的制动盘在运用过程中未发生散热筋裂纹故障,运用状况良好。In view of the crack fault of the cooling ribs of a brake disc for 25T passenger car,this paper analyzes the structure,stress condition and fracture failure of the cooling ribs from the position of the fault cooling ribs on the brake disc,determines the formation mechanism of the fault,and puts forward the optimization measures from the perspective of the structure design and forming process of the cooling ribs.The optimized brake disc has no crack fault of cooling ribs during operation,and the operation is in good condition.
