“…The analytical vehicle dynamics models derived by equations of motion usually use static stiffness as the LS suspension stiffness 14 alternatively. The Bouc-Wen model 15,16 and the generalized Maxwell-slip damper (GMD) model 17 were used to describe the LS hysteresis characteristics caused by friction. However, those methods can describe the elastic characteristics of LS, but they are not capable of stiffness optimization.…”

In vehicle multi-body dynamics (MBD) modeling, the stiffness parameterization of leaf spring (LS) is an unavoidable challenge regardless of the selection of modeling methods. On the contrary, the parameterization of Coil Spring (CS) stiffness is easy to achieve by adjusting the scale factor. Therefore, a novel LS stiffness parameterization method by treating the suspension stiffness as an intermediate variable through a CS stiffness is proposed based on the virtual displacement theory. The proposed method is then implemented in the vehicle-level modeling of a commercial Van with front transverse leaf spring suspensions and rear longitudinal parabolic leaf spring suspensions. The MBD model is validated by natural frequency tests and suspension stiffness simulations. Furthermore, the vertical acceleration of the car body is also verified. Results show that the root mean square (RMS) values of body vertical acceleration in the equivalent CS model are just slightly lower than that in the LS suspensions. The applicability and capability of the proposed method are proven to address the limitation of LS stiffness parameterization in MBD modeling. It lays the groundwork for efficiently simulating the LS suspension in vehicle ride and handling design and optimization.

“…Understeer and roll characteristics were improved by changing the diameter of the anti-roll bar. Wu et al 4 proposed a generalized Maxwell-slip dampers (GMD) model to analyze the influence of the hysteresis characteristics of leaf springs caused by contact and friction between the spring plates on the vibration performance of the vehicle body under different road excitation. Some scholars have designed specific suspension structures to improve the handling stability and ride comfort of vehicle.…”

This study focuses on the relevance of bushing stiffness for E-type multi-link suspension to handling stability and ride comfort of vehicle. The influence of bushing stiffness on suspension performance is illustrated theoretically from the force point of view. The principle of the influence of bushing stiffness on vehicle handling stability and ride comfort is described. In simulation study, the influences of specific bushing stiffness on vehicle handling stability and ride comfort are analyzed. The simulation results show that the bushings stiffness of the upper and lower control arm of the suspension significantly influences vehicle handling stability and the influences are more significant in the low frequency range. The vehicle ride comfort on the random road is mainly influenced by the bushing stiffness of the top mount of shock absorber, and on bump road by the bushing stiffness of the trailing arm mostly. Finally, the NSGA-II and MOPSO algorithms are used to optimize handling stability and ride comfort. The optimization results show that the handling stability and ride comfort of the vehicle could be improved with reasonable adjustment of the bushing stiffness. The results obtained in using the NSGA-II algorithm are more suited to the optimization requirements of this study.
