Abstract
Superior NVH performance in vehicle design requires optimizing mount rates of a body-on-frame vehicle for various criteria like the rough road shake, noise and impact harshness & boom etc. These vehicle characteristics may necessitate trade-off studies, as they may require directionally opposite changes in the vehicle tuning.
This paper deals with the trade-off between rough road-shake and impact harshness parameters optimized by tuning the mount characteristics. Simulation results indicating various response characteristics for rough road shake, noise and impact harshness & boom are monitored.
A complete vehicle simulation model is used to perform mount optimization for road-shake and impact harshness. A condensed Component Mode Synthesis (CMS) model is used for scanning the design space with the help of DOE sampling techniques. These results are utilized by employing approximation techniques to create response surfaces. The response surfaces are optimized to achieve an optimal solution for both the road-shake & impact harshness. The results obtained provided an insight into the design domain with respect to the trade-off between shake and harshness.
