Abstract: A finite element analysis (FEA) was built using the software ANSYS. The model was used to perform the composite structures, as well as the mechanism overall statics simulation analysis. Meanwhile, a simulation of fluctuating wind effect on the system was conducted based on the theory of transient dynamics. The simulation analysis of the mechanism and the solution programs were introduced in detail. The composite structure and mechanism overall statics simulation results provides the evidence that the mechanism has met the design requirements. Moreover, the FEA results indicated that the frequency generated by the fluctuating wind was less than natural frequencies. As a result, the resonance will not happen for the mechanism. After comparing the results of the two simulations, it was found that fluctuating wind effect on mechanism has a greater impact.
