In order to satisfy the development trend of light-weighting design of large crawler crane, beginning with analysis of the influence of wind load on the performance of large crawler crane truss structure, the numerical simulation of the crawler crane typical truss structure is carried out by fluid dynamic analysis software. Under the limit working condition of wind blowing, the impacts of steady-state wind field and dynamic-state wind field to the performance of truss structure are calculated separately and the coupling effects of various rods of truss structure in the wind field are analyzed. The simulation and calculation results indicate that the wind load calculation method for the crane truss structure in the existing design criterion of crane truss structure is too conservative, which make the self-weight of the truss structures much bigger. Research results in the paper provide certain reference for the light-weighting design of large-scale crawler crane truss structure.
