Abstract: |
Systematic finite element (FEM) simulation analysis of gantry friction stir welding system for the tank?dome of?heavy launch?vehicle has been done in this?paper based on ANSYS. According to the analysis results, the main structure of movable gantry was optimally designed and the structure?layout of the gantry friction stir welding system was confirmed. Through the researches of the FEM simulation analysis and optimization design, the structural performance and the design?reliability of the machine was improved. The?findings of the researches in this paper could reduce the development cycle and operating cost, and then provide important technical references to the follow-up engineering?implementation of the friction stir welding system. |
