Development of System Level Testing Method for Passenger Car Engine Mounts

Engine mount is an integral part of any Internal Combustion engine. It is the medium which isolates the vibrations coming from engine being transferred to the chassis or body of vehicle. Engine or power plant is the main source of unbalanced vibrations. The major role of an engine mount is to minimize those vibration levels, improve ride comfort and increase the life of an engine and its accessories. Most of the OEM’s are validating the engine mounts in virtual environment as FEA analysis software. In this paper detailed procedure of testing of Engine mount at system level is presented. This work determines the development of test procedure for passenger car engine mounts in the Laboratory by using Multi-axial environment which also explains the details of truly Multi-axial test rig development, Drive file creation and Durability Testing with the maintained vehicle conditions by simulating the field conditions in the laboratory. Results of simulation and durability also enclosed. This work reduces the lead time development of engine mounts of passenger vehicle.
