Based on the Finite Element Method, the suspended platform of temporarily installed suspended access equipment was simplified and the special connection positions were dealt with rigidization and coupling, thus the finite element model of suspended platform was established. Analyzing major structures of finite element model in different section dimensions, the reasonable scheme could be ascertained and the section dimensions of major structures in different materials could be obtained. Combining with the test results, the rationality of finite element analysis could be proved. The study could provide reference for the similar products on design and development.

In this subject, there were the Analysis Parametric Design Language (APDL) and optimization of the design process to be introduced. Based on APDL and optimization design module of ANSYS, the structure of suspension mechanism was optimized and the extraction of the maximum stress of the beam structure was realized according to the actual work of the large load temporarily installed suspended access equipment. The optimization of product structure was achieved and the utilization of materials was improved by the minimum structural quality of the suspension mechanism as the optimization objective. The study could provide reference for the similar products on design and development.
