摘要
将圆柱形螺旋弹簧设计中的部分常用公式组合成一组仅与弹簧指数Ｃ有关的公式，并将Ｃ＝４～１４代入计算而获得一套参数表，由此，可提高圆柱形螺旋弹簧的设计效率。
Part of formulas in the design of cylindric helical spring are combined into a group of formulas only relating to the spring index C and a set of parameter list can be acquired by introducing C= 4～14 into the calculation. Therefore we can enhance the design efficiency of the cylindric helical spring.
