Summary:

Last decade has been era of environmental awareness. Variousprograms have launched for making devices and applianceseco-friendly. This initiative has lead automobile industry towardhybridization and now total electrification of vehicles. Aselectric motor is being added to automobile as a prime mover, dueto high frequency vibrations along with higher torque electricmotor needs to be isolated properly and carefully as thisvibration can damage other automobile parts. Dynamic response ofelectric motor is different from response of IC engines, so use ofengine mounting design method may not be suitable for designingmounting system for electric motor. First, both 4- point and 3-point mounting system are considered for analytical andexperimental investigation of force and displacementtransmissibility. Position and orientation of elastomeric mountsplays important role in design of mounting system for electricmotor. Mounts used in passive vibration isolation are made up ofelastomeric material, which are resilient in nature. So if force isapplied on mount it will deflect in direction of force thereforeideal positions for elastomeric mounts are found by drawing freebody diagrams (FBD) of force distribution on mount due to electricmotor at various position in a single plane. Response of these twoconfigurations are then compared. This paper focuses on deliveringsystematic approach for finding optimal positions, orientation& number of elastomeric anti-vibration mounts to achieve propervibration isolation and decoupling of vibration modes
