摘要
基于ANSYS仿真分析平台对重型运载火箭龙门式箱底搅拌摩擦焊接系统进行了系统性的有限元仿真分析,根据分析结果对移动式龙门的主体结构进行了优化设计,确定了龙门式箱底搅拌摩擦焊接系统最终结构形式。通过有限元仿真分析及结构优化研究,进一步提升了整机结构性能及设计可靠性,降低了系统开发周期及运行成本,为后续工程化实施阶段提供了重要的技术参考。
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.
