| Abstract: | Finite element analysis was carried out of the deformation and stress distribution of the bridge structure of a certain 200t,20m metallurgical crane by means of ANSYS,a software.It is found that the maximum flexibility,static Von Mises equivalent stress,and natural vibration frequency of first step of the crane conform to design specifications.Meanwhile,ANSYS results are compared with those of field test,which provides a theoretical basis for evaluating the reliability of loading capacity. |
