Content
Low frequency structure borne booming noise is one of the important ride parameter and has become a key differentiator in the modern vehicle development. In most of the vehicles, windshield vibration is main concern for booming noise. One of the ways to get rid of this is to reduce the energy transferred from windshield to cavity by stiffening windshield mounting structure.
The concept of open section plenum is evolved to meet pedestrian impact requirements which in turn affect noise, vibration and harshness (NVH) performance of vehicles. Open section plenum affects windshield structure to cause Boom and Powertrain noise concerns.
This paper mainly focuses on improving the boom / powertrain noise performance by stiffening windshield mounting structure while still meeting the pedestrian impact requirements. An outcome of the study can be used as design guidelines for future vehicle development programs to meet NVH targets in an early stage of the program.
