摘　　要：机械零件或加工用工具的尺寸、形状或材料性能都会因某种因素的影响导致失效问题的发生^([1、2]),只有客观地评价可能导致产品生产的全部潜在失效形式,才能成功地设计并生产出能够防止过早出现失效现象的产品。现通过采用现代化的分析技术手段对燃机透平轮盘用拉刀在前期试验验证过程中突然断裂的问题进行了深入分析和探讨,以作为后续提升拉刀制造水平,避免重大产品质量事故的发生提供科学的判断依据。The size,shape or material performance of the mechanical parts or the processing tools will lead to the occurrence of failure influenced by some factors.Only all potential forms that may lead to the production failure of the products are objectively evaluated,the products that can prevent from premature failure can be designed and produced successfully.This paper deeply analyzes and discusses the sudden fracture problem of broach for gas turbine wheel disk in the process of preliminary test and verification by using modern analysis technology,which provides the scientific judgment basis for the subsequent improvement of broach manufacturing level and the avoidance of major product quality accidents.
