Optimization of the interface between the powerplant and vehicle frame/body is critical to obtaining superior interior structureborne noise and vibration characteristics in the vehicle. This paper demonstrates the combination of new and existing simulation/experimental methodologies for powerplant integration, including results from case studies.
Multi-body simulation based methodologies are used to optimize the location, number, and type of powerplant mounts on a vehicle, taking into account the input forcing from the engine and frequency-dependent mount properties. Upon obtaining the first prototype vehicle, a procedure to evaluate the effectiveness of the powerplant mounts using a vibrational power flow technique, is described. The influence of mount bracket resonances on interior vehicle sound is shown and a new procedure to optimize mount brackets, provided. Finally, the use of noise path analysis and interior noise simulation (INS), in relation to optimizing the structureborne noise/vibration, is presented.
