NURBS方法是目前塑性成形三维数值模拟领域最具代表性的方法 ,具有强大的造型功能 .研究了采用NURBS方法构造曲线、曲面方程和网格生成及插值生成曲面的问题 ,并利用FORTRAN语言编制了描述模具型腔表面的程序 .
NURBS method is the most representative method in the field of plastic forming three-dimensional numerical simulation and has a powerful modeling function.NURBS method is used to construct curves, surface equations and mesh generation and interpolation to generate the surface, and the use of FORTRAN language Describe the mold cavity surface procedures.
