| Abstract: | Abstract: The structure strength of the boom under 4 cases is carried out by MSC/Nastran and its stability are checked.The calculation methods of load and the applied methods of constraint conditions are intruducted in this paper. It can be conclused that by FEM analysis that the same type design and strength analysis of the boom structure has a certain reference value.The results show that the structural strength and stability of the crane meet the regulatory requirements. |
