摘要
本文从有限元计算和应力应变测试的角度出发,提出通过有限元计算或者应力应变测试,得出起重机主梁的主要受力点,提出一种起重机械主梁再制造毛坯的简化检验检测方法,对起重机主梁再制造有极大的参考意义。
From the perspective of finite element calculation and stress-strain test, this paper proposed to obtain the main stress points of the crane girder by finite element calculation or stress-strain test, put forward a simplified inspection and test method for remanufacturing blank of the crane girder, which has great reference significance for crane girder remanufacturing.
