A Systematic Approach Towards Engine Mounting System Vibration Isolation Performance Validation in Commercial Vehicles

Engine mounts and mounting brackets play a critical role in determining NVH performance of a vehicle. A lot of work has been done in the area of virtual simulation using FE models to study engine mounting system performance and its impact on vehicle level performance. An overall approach towards engine mounting system validation at vehicle level is also very critical to validate simulation results in a prototype based on which further refinement work will be carried out. In this paper a detailed procedure for engine mount and mounting bracket physical validation at vehicle level is presented. Various tests to be performed at vehicle level to quantify engine mount and mounting bracket performance parameters are discussed in detail along with measurement procedures and techniques. Test results are interpreted and their impact on overall performance is also explained. These test results will help design engineers to further improve engineering parameters of mounts and mounting brackets. An attempt is also made to integrate impact of engine mounting system performance on vehicle level tactile vibrations. Adherence to this systematic approach will reduce the lead time of development and provide opportunity to identify key areas to concentrate on in engine mounting system design at early prototype stage.
