中文摘要:文章通过主应力法计算出反挤压空心坯料的所需载荷公式,采用Deform-3D软件对两种不同实验方案进行模拟,结果表明,反挤压空心坯料能有效降低载荷和单位变形力。通过试制铝合金轮辋证实了这一理论。
英文摘要:The load formulas of Anti-extrusion of hollow billet were calculated by Slab method.Two different programs were also simulated by Deform-3D software.The results show that,Anti-extrusion of hollow billets can effectively reduce the load and unit deformation force.The trial of Aluminum alloy wheels confirms this theory.
