利用UG/OPEN API在UG中添加圆柱弹簧几何造型功能
Supplement of geometric formation function of cylindrical spring to UG by using UG/OPEN API
【摘要】 针对UG中缺少圆柱弹簧的直接造型功能,而且在UG中生成弹簧造型过程复杂繁琐的问题,作者通过利用NURBS曲线逼近螺旋线的方法,将NURBS曲线与UG二次开发有机地结合起来,程序化地生成圆柱弹簧,实现了在UG中直接生成圆柱弹簧造型的功能.
【Abstract】 There is no function of directly creating cylindrical spring in UG modeling, and it is very complex to create cylindrical spring in UG by other means. The authors deduce and discuss how to use NURBS curve to approximate a curve to helical line and how to create cylindrical spring directly, so that NURBS curve and secondary development of UG are combined to supplement the geometric formation function of creating cylinder spring to UG.
