关键词:钢管减径;机架结构;有限元分析;力学特性AbstractThis paper mainly studies the mechanical characteristics of the steel pipe reducing process and the influence of the rack structure
The finite element analysis software is used for simulation analysis to explore the influence of different parameters on the reducing process
The research results show that, in the rack structure, the use of angle steel can significantly improve the overall stiffness and stability; in the steel pipe reducing process, reducing the reducing amount and increasing the reducing times can reduce stress concentration and improve
