摘　　要：在力学理论分析的基础上,对桥式起重机主梁进行有限元分析,具体包括危险工况下的静力学分析、简支约束和自重载荷条件下的模态分析与谐响应分析。通过有限元分析,得到桥式起重机主梁可能出现疲劳损伤的失效点,为后续疲劳检测提供依据。On the basis of the theoretical analysis of mechanics,the finite element analysis of the main beam of the overhead crane was carried out,including the static analysis under dangerous condition,the modal analysis and harmonic response analysis under the condition of simply supported constraint and self-weight load.Through finite element analysis,the failure point of the main beam of the overhead crane that may be fatigue damaged was obtained,which provided a basis for subsequent fatigue detection.
