• Calculate the maximum deflection and spring constant using the following formula. | |
• Maximum deflection Maximum deflection (mm) = S × maximum deflection factor (%) | • Spring constant(reference value) Spring constant (N/mm) = reference spring constant × 10/S |
Maximum deflection(mm) = 498×58% = 288.84 | Spring constant(N/mm) = 20.50 × | 10 | = 0.41 |
