- Intelligent tower crane has large structure deadweight. The service life of the whole machine is dependent on the life of the structure. As a result, the metal structure should be designed by using correct and reasonable methods to obtain excellent fatigue properties. And it can guide the design, manufacturing, use and maintenance process for crane. And it has great significance to prevent the fatigue fracture accident. The theoretical mechanics and material mechanics theory is a semi-theoretical semi-empirical traditional design method, but it is not the suitable design method. Now, the finite element method, fracture mechanics, the boundary element method, the optimization design method, reliability design and fatigue design methods are widely used in the structure design of crane. In this paper, the intelligent tower crane structure is analyzed by finite element modeling. According to the actual situation, crane structure is studied by finite element statics analysis. Then mechanical property of this kind of structure is analyzed in detail. And the weak links of the structure are found out. The residual life can be estimated finally. As a result, designers can comprehensively understand the fatigue life distribution of different parts in the crane. Therefore, they can provide intuitive and comprehensive basis for comparing the advantages and disadvantages of different design schemes and fatigue performances for design improvement.
