Dynamic modeling and elastic characteristic analysis of the transverse leaf spring suspension

The transverse leaf spring (TLS) suspension has simple structure, convenient installation and low cost. And the suspension stiffness is optimized by changing the TLS fixing bracket position without changing TLS size, which makes the TLS suspension have higher application prospect. The dynamic modeling method is proposed for analysis of elastic characteristics of the TLS suspension. The trend of the TLS stiffness is theoretically expounded. And the stiffness, natural frequency, damping characteristic and vibration of the suspension are simulated and tested. The comparative analysis shows that the precision of numerical results is high, which also shows that the TLS suspension modeling method is correct. The results provide a basis for grasping the TLS stiffness trend and the suspension dynamic characteristics.
