| 摘 要： | 采用ANSYS有限元程序分析软件，对出现裂纹的起重机主梁的不同长度补强板进行分析，研究了起重机主梁应力及变形情况。结果表明，只有采用一定长度的补强板，才可消除起重机主梁裂纹的扩展趋势，从而保证起重机的安全运行。

| Abstract: | Using the ANSYS finite element program analysis software, this paper analyzee different lengths of reinforced board on the crane girder with crack and studies the girder's stress and deformation. The results indicate that,only by using an appropriate length of roinforced board can the expanding trend of the crack on the crane girder be checked and the safety of the crane running be ensured. |
