针对鱼雷罐车架裂纹故障，利用力学分析软件对车架进行分析，得到车架在不同载荷作用下的应力分布情况，找到车架的应力集中点，提出对车架结构进行改进和优化的方案，降低车架整体应力水平，从而减少裂纹发生的次数，延长车架的使用寿命。

In viewing of the fault of frame crack of torpedo tanker,the frame was ana-lyzed by mechanical analysis software,of which the stress distribution under various loads was gotten and the stress concentration point was found.Then the solution of im-provement and optimization of the frame structure was proposed,which reduced the o-verall stress level of the frame,reducing the times of crack occurred,and prolonged the frame's using life.
