以圆管变形为管球相间零件为研究对象
对液压成形这种新工艺进行研究.采用计算机数值模拟与试验相结合的方法
分析了圆管液压成形过程.管件液压成形主要有褶皱和破裂两种失效形式
而成形控制中最主要的参数之一是压力
即管件内部压力和轴向压力.在对不同加载路径进行分析后
得出模拟结果与相同条件下的实验结果比较吻合的结论.研究表明了液压成形工艺中加载路径(内压力与轴向压力的配比关系)的重要性
同时也证实了用计算机模拟仿真液压成形过程具有一定的可靠性.
Hydroforming of bulging in the middle of a tube is focused on
and numerical simulations are carried out for the tube hydroforming process to provide reference for the practical forming experiments.Two main failure types in the process of hydroforming are wrinkling and bursting.Controlling of hydroforming process mainly depends on interior pressure and axial feeding.Simulation results are compared with experimental results in the same conditions and the agreement is obtained after analyzing different loading paths.The study shows the importance of loading path in the process(exp
interior pressure and axial feeding).It also indicates that the hydroforming process can be simulated with good reliability by computer.
