对于螺旋弹簧设计,在确定弹簧其他尺寸之前,先要确定弹簧线大小,而确定弹簧线的大小,通常需要繁琐的积分计算。当只知道所施的力和孔径时,这里介绍一种简化的计算程序,供快速选择弹簧尺寸和材料之用。大多数的使用情况,被确定的弹簧尺寸应使弹簧与孔具有线直径之半的直径间隙,那末,孔直径Φ和线直径d之间的关系为: For helical spring designs, the size of the spring wire must be determined prior to determining the other dimensions of the spring. Determining the size of the spring wire usually requires a cumbersome integration calculation. When only knowing the applied force and aperture, here’s a simplified calculation program for quick selection of spring sizes and materials. In most applications, the size of the spring is determined so that the spring and hole have a diametrical clearance of half the diameter of the wire. Then, the relationship between the diameter of the hole, φ, and the diameter, d, is:
