Helical Spring Formulas
- The formula for the surge frequency (fs) in a helical spring under variable loads is: fs = (1/2) * √(k/m), where k is the spring stiffness and m is the mass of the spring.
- The formula for the maximum deflection (δmax) of a helical spring under static load is: δmax = (F_max * L) / (n * E * A), where F_max is the maximum applied force, L is the length of the spring, n is the number of coils, E is the modulus of elasticity, and A is the cross-sectional area of the spring wire.
- The formula for the shear stress (τ) in a helical spring subjected to a static load is: τ = (8 * F_D) / (π * d^2), where F_D is the design force and d is the diameter of the spring wire.
