About Spring Rate Calculator
What is Spring Rate?
Spring rate is the force required to compress or extend a spring by a unit distance, typically expressed in N/mm, lbf/in, or kgf/mm. It's a crucial parameter that measures spring stiffness and directly affects vehicle handling and ride comfort.
Key Components
- Applied Force - The external force acting on the spring
- Displacement - The compression or extension distance under force
- Elastic Coefficient - The inherent elastic properties of the material
- Geometric Parameters - Wire diameter, coil count, spring diameter, etc.
Why It Matters
Spring rate is a core parameter in suspension system design, affecting vehicle handling, comfort, and safety. Proper spring rate selection achieves the optimal balance between handling performance and ride comfort.
