Abstract:
Performance criterion of local stiffness in BIW(Body in White) for NVH(Noise, Vibration, and Harshness) and R&H (Ride and Handling) are presented in this study. A process to develop the local stiffness of the vehicle body has been established for the performances. For handling performance, not only suspension bush stiffness but local stiffness in BIW structure is important. However, there is no good standard to describe handling performance using BIW local stiffness. In this paper, a new evaluation standard for local stiffness in BIW is developed and verified considering actual vehicle driving condition for handling performance. Also, new evaluation process regarding local stiffness in BIW for vibration transmissibility is presented. The new process is developed considering optimal relation between connecting bush stiffness and BIW local stiffness. It is shown that the interior noise of the vehicle is reduced by applying the evaluation process, which is verified through several cases.
