Parameters

Allowable Shear Stress ([τ])

The maximum permissible shear stress for the spring wire material.

Shear Stress (τ)

The calculated shear stress in the spring wire under load.

Shear Modulus (G)

The material property representing stiffness in shear.

Mean Coil Diameter (D2)

The average diameter of the spring coil.

Spring Index (C)

The ratio of mean coil diameter to wire diameter (C = D2 / d).

Minimum Working Load (P1)

The minimum load applied to the spring during operation.

Maximum Working Load (P2)

The maximum load applied to the spring during operation.

Deformation under Min Load (F1)

The spring deflection under the minimum working load.

Deformation under Max Load (F2)

The spring deflection under the maximum working load.

Height under Min Load (H1)

The height (or length) of the spring under the minimum working load.

Height under Max Load (H2)

The height (or length) of the spring under the maximum working load.

Height under Limit Load (H3)

The height (or length) of the spring under the limit load.
