Precisely calculate the axial deflection of helical springs under load. This essential tool helps engineers and designers determine spring displacement for various applications, ensuring optimal performance and safety in mechanical systems.
Formula:
The axial deflection (δ) of a helical spring can be calculated using the following formula:
δ = (8 * P * D³ * n) / (G * d⁴)
Where:
- δ = Axial Deflection (mm or in)
- P = Axial Load (N or lbf)
- D = Mean Coil Diameter (mm or in)
- n = Number of Active Coils (dimensionless)
- G = Modulus of Rigidity (Shear Modulus) of the spring material (N/mm² or psi)
- d = Wire Diameter (mm or in)
