What are the parameters of a compression spring? First of all, look at the formula:
The meaning of each item in the above formula is:
G = Modulus of elasticity in shear [MPa, psi] (G value: wire 8000, stainless steel 7200)
d = Wire diameter [mm, in]
n = Number of active coils [-]
D = Center diameter [mm, in]?
k = spring constant [N/mm, lb/in]
This formula is for the spring stiffness, which multiplied by the working stroke equals the working force of this spring.
Through the above formula, we can conclude that the parameters of a compression spring must consist of: material, wire diameter, center diameter, effective number of coils, total length of the spring, working height, and demand strength. If there is no special requirement for the strength of the spring, you can not provide the parameters of the working height and demand strength of the spring.
I hope this helps! Thank you!
