Quick Simulation Method for a Design Modification to Reduce the Car Cabin SPL as Well as the Mass of Sound Proofing Material Using a Similar Car HSEA Model
Published September 29, 2010 by Society of Automotive Engineers of Japan in Japan
This paper discusses a quick design modification simulation method applied to the minivehicle. In this method, a HSEA model for this minivehicle is not developed, but instead, the minivehicle of similar form HSEA model is determined as the model closely resemble to this minivehicle. Some detailed methodology describing the process of the reduction is shown in this paper. The simulation result is used to create a real design modification in this minivehicle, and its effect is tested through a road test. The cabin SPL improvement is found to be comparable to this calculation result.
