The image above represents spring torque. To calculate spring torque, three essential parameters are needed and these parameters are Force Independent Constant (Kw), Compressive Force (F), Centre to Centre Diameter of Spring (D) and Cross-section Diameter of Spring (d).
The formula for calculating spring torque:
τ = Kw(8FD/πd³)
Where:
Ï„ = Spring Torque
Kw = Force Independent Constant
F = Compressive Force
D = Centre to Centre Diameter of Spring
d = Cross-section Diameter of Spring
Let’s solve an example;
Find the spring torque when the force independent constant is 12, the compressive force is 24, the centre to centre diameter of spring is 11 and the cross-section diameter of spring is 44.
This implies that;
Kw = Force Independent Constant = 12
F = Compressive Force = 24
D = Centre to Centre Diameter of Spring = 11
d = Cross-section Diameter of Spring = 44
τ = Kw(8FD/πd³)
So, τ = 12(8(24)(11)/π(44)³)
Ï„ = 12(2112/Ï€(85184))
Ï„ = 12(2112/267613.428)
That is, Ï„ = 12(0.0078)
Ï„ = 0.0947
Therefore, the spring torque is 0.0947 Nm.
