摘　　要：研究应力测试技术在起重机械结构安全评估中的应用,以桥式抓斗卸船机为例,根据结构有限元分析结果与结构实际情况进行测试,分析各测点测试数据及应力时间历程图,明确卸船机结构安全状况,指出检修与检测时结构重点关注位置,为卸船机金属结构设计、使用与安全评估提供理论参考。The paper studies the application of stress testing technologies in the safety evaluation of the hoisting machinery structure. Taking the bridge grab ship unloader as an example,the paper performs tests based on the finite element analysis result and actual structural condition to analyze the test data and stress-time history diagram for measuring points,determine the safety condition of the ship unloader,and point out the key positions of the structure during overhaul and testing,providing theoretic reference for the design,operation,and safety evaluation of the metal structure of the ship unloader.
