弹簧|压缩弹簧计算基本公式：

c = 弹簧指数(c=D/d; c=D/b) [-]

b = 线宽[mm, in]

d = 线径[mm, in]

L0 = 弹簧自由长度[mm, in]

LH = 弹簧挂钩高度[mm, in]

LK =有效截面长度[mm, in]

n = 工作线圈数[-]

p = 线圈间距[mm, in]

s = 弹簧变形量[mm, in]

Ψ= 形状系数 [-] (e.g. DIN 2090)

t =弹簧材料拉伸应力 [MPa, psi]

t0 = 内应力 [MPa, psi]

D = 弹簧中心直径[mm, in]

F = 弹簧负载[N, lb]

F0 =内应力[N, lb]

G = 剪切弹性模量[MPa, psi]

h = 线高[mm, in]

k = 弹簧系数[N/mm, lb/in]

Ks = 弹簧曲线纠正因数[-]
