Stress Analysis of the Whole Structure of Tower Crane Based on Finite element method

In this thesis,QTZ4010 tower crane was taken as the research object and stress analysis of the overall structure was taken as the main objective.On the basis of the analysis of its overall structure and working conditions,a finite element model of the tower crane was built.And five typical working conditions were chosen,stress analysis of the finite element model of its overall structure was done.Finally,the optimization design plan of the overall structure was proposed.
