The image above represents force independent constant. Two essential parameters are needed to calculate force independent constant: Centre the Centre Diameter of Spring (D) and the Cross-section Diameter of Spring (d).
The formula for calculating force independent constant:
Kw = 1.60(D/d)-0.14
Where:
Kw = Force Independent Constant
D = Centre to Centre Diameter of Spring
d = Cross-section Diameter of Spring
Let’s solve an example;
Find the force independent constant when the centre to centre diameter of spring is 44 and the cross-section diameter of spring is 11.
This implies that;
D = Centre to Centre Diameter of Spring = 44
d = Cross-section Diameter of Spring = 11
Kw = 1.60(D/d)-0.14
Kw = 1.60(44/11)-0.14
So, Kw = 1.60(4)-0.14
Kw = 1.60(0.82)
Kw = 1.317
Therefore, the force independent constant is 1.317.
