The Finite Element Analysis and Optimization of Subway Steel Structure Work Platform Based on Workbench and Pro/E in a Subway

摘要

The static and stability analysis of steel structure were taken according to steel structure work platform's requirements and structural characteristics in a subway parking space by using the software model which is established by Pro/E software and implanted into the finite element analysis software ANSYS Workbench. The maximum deformation and stress in design load of the steel structure were calculated and the linear stress strength analysis of the key parts was carried out, also both the analysis and testing of the supporting pillar's stability were performed. The results show that the structure model established by Pro/E and the calculation method are reasonable. Moreover, the calculation results are of high accuracy. The profile size is properly chosen and the structure bearing capacity and deformation meet the design requirements.
