| Abstract: | In the ET phase of the development of a light passenger vehicle, finding the roof and side structure stiffness is not enough that the structure vibration exceed the target when the vehicle runing and dosing door.Through a lot of NVH test and finite element analysis to find the reason of the issue aboved and re-design a new body structure to improve the structure stiffness. Finally, this problem was solved perfect. |
