摘要
为对薄壁不锈钢管环压接头软膜胀形的成形过程进行分析,以ANSYS中LS-DYNA模块为基础进行模拟,分析了凸模不同加载速度和位移对管件的影响,与实验所得的数据进行对比分析可知,在加载过程中,凸模位移加载量一定的条件下,凸模的加载速度与管坯成形后的最小壁厚呈反比关系。薄壁不锈钢管的最小壁厚出现在承口起包处,最大壁厚出现在管件根部,而且在凸模以40 mm/s速度加载40 mm的位移量时,薄壁不锈钢管环压接头能够在成形质量上达到最佳。
The paper briefly analyzes the ring joint soft bulging forming process of thin-walled stainless steel tube,based on the LS-DYNA module in ANSYS,the effects of different loading speeds and displacements on the pipe fittings are simulated and analyzed. The data obtained from the experiments are compared with the experimental results,in the loading process,under certain conditions,the load speed of punch is inversely proportional to the minimum wall thickness of tube blank. The minimum wall thickness of thin-walled stainless steel tube package appears in the socket,the maximum wall thickness of pipe in roots,and in the punch to the displacement speed of 40 mm/s loaded 40 mm,the thin-walled stainless steel pipe ring joint can achieve the best forming quality.
