We use Pro/ENGINEER Mechanica software to carry on finite element analysis for the initial design. The maximum stress zone and the maximum deformation zone and the values are achieved under the superimposed load and the manned conditions. The results of finite element analysis can verify the reliability of the initial design. The material of platform is optimized based on the finite element analysis results. Using modern design method can not only ensure the supporting work safety, but save materials and reduce the energy consumption.
