Transmission Study on Dynamic Characteristics of Front Suspension LCA Bushing

Abstract:

This paper simplified the wheel-Lower Control Arm-frame system into a two DOFs vibration system and analyzed its transmission characteristics by modeling the LCA rubber bushing in Kelvin-Voigt model, Zener model and Berg model, respectively. The results show that the system with Berg model shows obvious amplitude-dependent characteristics. Its magnitude and frequency at the peak of the transmission curve change as the excitation amplitude changes. The system with Kelvin-Voigt model or Zener model shows none amplitude-dependent characteristics. It’s more effective and more exact to model the LCA rubber bushing in Berg model than the others.
