disk spring

The smelting and rolling of 38Si7 hot -rolled spring rounds is according to DIN 17221 - 99.

38Si7热轧弹簧圆钢是按照德标DIN17221—88的要求冶炼、轧制、出口,用于制造钢轨紧固件及弹簧。

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.

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。
