App description

Spring coefficient calculation

Enter the value, click on "Calculate" and the result will be displayed.

Calculation formula

\(K=\frac {G×d}{8×C^3×N}\)

  • K = spring coefficient
  • d = spring wire diameter
  • N = number of effective coils
  • G = rigid modulus
  • C = spring index

Usage example

Input data: spring diameter D: 0.9 m;

spring wire diameter d: 0.1 m;

rigid modulus: 5 N/m2;

effective number of coils: 10,

Click “Calculate” to display the result.

Output: spring stiffness, spring factor K is 0.00000857.
