Robustness of mount systems for idle NVH, Part II: pendulum mounts
by Mohammad Sirafi, Yin-Ping Chang, Mohamad S. Qatu
International Journal of Vehicle Noise and Vibration (IJVNV), Vol. 2, No. 4, 2006

Abstract: The pendulum mounting strategy in east-west powerplant configurations is based on two major mounts, one at the engine side and the other at the transmission side and one or two roll-restrictors. This system is used in many of today's vehicles, particularly those with lighter powertrains. This paper discusses the variability of the modal decoupling strategy as a function of variations of the powertrain pendulum mount stiffness, location and inertia properties. In addition, this paper discusses impact of mass and inertia variations. A six degrees of freedom model is used in the analysis. Detailed design of experiment studies are described.
