“…Based on the complex variable moving least squares (CVMLS) approximation and locally symmetric weak form, professor Dai baodong and others proposed a complex variable meshless local Petrov-Galerkin (CVMLPG) method for solving two-dimensional potential problems [13]. Doronin et al [14] proposed a technique for reverse analysis of analytical and numerical estimates of the stress state, which logically explains the differences in estimates (results) by proposing a set of plausible factors (causes) and then systematizing and generalizing the latter. In order to improve the stability of nuclear power crane, Qin et al proposed a new vibration analysis and control method based on magnetorheological fluid damper and switch algorithm control strategy.…”

All-terrain crane is indispensable for hoisting land wind turbines safely. Because the lifting height, load and lateral dimension during the safe hoisting process of the wind turbine are relatively large, the special jib structure of the all-terrain crane for hoisting wind turbine safely is adopted to solve the problem of interference between the crane jib and the wind power equipment. In view of the unfavorable stress of special jib structure and wind load of special jib structure working environment. On the one hand, the overall finite element model of the all-terrain crane jib for hoisting land wind turbines is established. On the other hand, to combine with the actual load in the lifting process and study the static and nonlinear performance and mode of the boom structure. At last, the mechanical properties of the jib structure are analyzed. This research is very important to improve the safety of wind power lifting.
