N2 - According to the spiral line space curved beam theory, helical spring force analysis model was set up, and shear deformation, rotational inertia and helix angle were taken into account, so the formulas for calculating stiffness were obtained. By introduction to correction coefficient, accuracy of job stress and strength analysis was improved. Finally, FEA results for design and verification of suspension helical spring show that the above formulas are accurate.
