半滑动式液压胀形汽车桥壳的数值模拟及成形实验OA北大核心CSCDCSTPCD
Numerical Simulation and Test of Half-sliding Hydroforming Axle Housing
对在不同加载路径下半滑动式液压胀形工艺中的管坯预胀形及终胀形过程进行了数值模拟,分析了不同加载路径下的管坯成形情况及其周向、轴向的壁厚分布,得到了预胀形管坯壁厚分布较好的加载路径以及终胀形时可确保成形合格样件的加载路径,并在普通液压机上进行了实验验证。
A numerical simulation of pre-bulging and final bulging of half-sliding hydroforming under the different loading paths was carried out.The hydroforming state and the wall thickness of tubeblank in the periphery direction and the axial direction were analyzed under variable loading paths,and the better paths were figured out,by which the wall thickness distribution was good for the pre-bulging and the qualified samples were obtained.The small automobile axle …查看全部>>
