Noise, vibration and harshness (NVH) has become an increasingly important attribute in vehicle engineering. At idle conditions, customer-perceived NVH is dominated by powertrain NVH. Powertrain NVH can be radiated engine noise or noise (and vibration) transmitted through the powertrain mounting system. This paper discusses the variability in the latter NVH as a function of the variability of the mount stiffness parameters. A simple six-degree-of-freedom model is used in the analysis. A detailed design of experiment studies was conducted. It is concluded that better control of mount stiffness parameters would result in improved prediction and performance of idle NVH.
