A Study of Design Methodology to Develop Improved Door System of a Vehicle
This research paper is about a systematic design methodology used to develop improved door system of a vehicle. With a variety of engineering analyses, a new structural design was derived and optimized. The previous door system required improvement of the following problems. First, the lower quality of a door system especially causes the performance degradation such as NVH. But it is difficult to have a robust structure because of the limitations of structural design and manufacturing technologies. Second, for a lightweight vehicle, it is necessary to construct a structure for saving weight while ensuring equal performance. Third, a structure for improving the openness and the visibility through the door is required for the convenience. An optimization structure capable of minimizing the door is needed. In order to solve these problems fundamentally, it was needed to design a new structure that considered all of these from the basic level in the following steps. Step1.
