At first step, the processor before the deformable body contact the end face of cone die cavity regarded as an extrusion process. The minification of core boss's cross-section regarded as compressibility of direct extrusion, which acted as definition factor when construct the Direct Extrusion Model element. Another step, the model element of flat punch extrusion on wedge piece process was constructed when propose the process of deformable body overflow die corner. In this way the spherical end face of blank looked as cone end face one, t he approximate treatment is one of originality innovation in this paper. At last, the two elements have been connected and constructed the model element of cone boss part's deformation in the open die forging.
对于锥形凸台成形的第一个特征时段,即坯料和锥形凸台型腔的端面接触之前的变形过程,本文将凸台的截面缩小率转换成挤压成形的压缩率并以此为界定,建立了不同截面缩小率时的锥形模正挤压的模型单元;对于锥形凸台成形的第二特征时段即锥形模的角部充满过程,在详细考察锥形型腔端面对变形过程影响的基础上,将变形体的球形端面近似成锥面建立了平冲头挤压楔形体的模型单元;最后将前述两种模型单元有机连结,构建了开式模锻中整个锥形凸台成形过程的定量描述。

Luneberg lens is a spherical lens which its permittivity varies with normalized radial coordinates. It is fabricated by using different homogeneous dielectric centrically layered media. The lens can focus a parallel beam of rays from any direction exactly at a point on the surface. If it is made by adding a reflecting surface "metallic cap", it is called Luneberg lens reflector. It can reflect incident wave into plane wave in incoming direction. It is usually applied in antenna, radar reflector,satellite-based, and mobile-communucation.
龙伯球透镜为一种介电系数与半径成一固定比例的球形透镜,大部分是由数层不同介电系数介电质组合而成,而其主要特性能够把入射波聚焦到球表面一点,假使在透镜表面处镀上一圆锥角金属层即为龙伯球透镜反射器,能把入射波依平面波的型态反射回原入射端,通常用於天线、雷达、卫星通讯、军事等方面。
