In literature [3] , the formula for the thickness of backing plate is deduced.
文献[3]推导出补强板厚度的计算公式,但补强系数的确定方式较粗略。
Using the ANSYS finite element analysis software,this paper analyzes reinforcement plate of different length welded to crane girder crack and find out the girder′s stress and deformation The results show that welding the appropriate reinforcement plate to the girder crack can eliminate crack expanding and assure crane safe operatio
采用ANSYS有限元分析软件 ,对因出现裂纹的起重机主梁而添加的补强板进行系列计算 ,得出修补后主梁裂纹的应力及应力强度因子的变化规律。
