Finite Element Analysis of 10t Gantry Crane Structure Strength

Yi Liu

Abstract

FEM is adopted to analyse the crane. Structural static strength of the 10 t indoors gantry crane for repair is calculated under five working conditions. The stress and deformation of crane are given. The results show maximum of crane occur in the section of grider and flexible crura when car is in the right limit state of crane. The maximum stresss is 152.8 MPa closing to allowable stresss of Q235 material. The safety factor of crane is relatively low. In the application of the cranes, the cleft is arised in section of girder and flexible crura. The results can be applied to design the crane.
