Robustness of mount systems for idle NVH, Part I: Centre of Gravity (CG) mounts
A key parameter for frequency or modal separation of the powertrain is the basic mount design. For East-West engine configurations, there are two fundamental arrangements of mounts: the CG and pendulum arrangements. This paper discusses the variability of the modal separation of the powertrain rigid body modes as a function of the variability of the mount geometry and property parameters as well as sub-frame mount stiffness values. Six and 12 Degrees of Freedom (DOF) models are used in the analysis. Detailed Design of Experiment (DOE) studies are conducted.(A)
