Parameters

Spring Material [τ]

A material property related to shear stress limit.

Spring Material τ

Another material property, possibly related to shear stress.

Shear Modulus (G)

A measure of a material’s resistance to shear deformation.

Wire Diameter (d)

The diameter of the spring wire material.

Mean Coil Diameter (D/D2)

The average diameter of the spring coils.

Spring Index (C)

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

Free Length (L0/H)

The length of the spring when no load is applied.

Solid Length (Ls)

The length of the spring when fully compressed.

Minimum Working Load (P1)

The load applied at the minimum working height.

Maximum Working Load (P2)

The load applied at the maximum working height.

Deformation under Min Load (F1)

The change in length from free length under minimum load.

Deformation under Max Load (F2)

The change in length from free length under maximum load.

Height under Min Load (H1)

The length of the spring under minimum load (H1=L0-F1).

Height under Max Load (H2)

The length of the spring under maximum load (H2=L0-F2).

Height under Limit Load (H3)

The length of the spring under limit load (H3=L0-F3).
