Structural analysis of boom type tower crane based on finite element method

This paper presents the static structural analysis of boom type tower crane using ANSYS. The FEM model of crane was established in ANSYS, the loads determined according to the specified calculation condition and relevant design specifications were applied on the FEM model. In the analysis of strength and stiffness of the crane, it is concluded that the operating stress of most members of crane is less than the allowable stress of the material, and the static stiffness of the crane and its members is also less than the allowable value, so the static strength and stiffness of crane is satisfied the requirements.
