Dynamic Properties Modeling Analysis of the Rubber-Metal Elements for Electric Drive

Abstract The gradual increase in the volume of electric vehicles leads engineers to solve completely new problems NVH (noise, vibration and harshness) One solutions is use rubber mounts hold motor vehicle’s powertrain. This article deals with a mount used insulate vibrations from propulsion system rest vehicle. Since produces different spectrum noise than internal combustion engine (it lower amplitudes, but wider frequency band), it necessary adapt design mounts. possibility using mathematical model that can be virtual vehicle model. It compares differences motor. From results measured on experimental model, parameters for FEM were identified. At end article, experiment are compared simulations.
