The present invention provides an underbody manufacturing method and a vehicle underbody. The method comprises the following steps of: determining dimensions of the vehicle underbody and underbody panels; selecting the underbody panels; putting the underbody panels in a stamping die for stamping to form concave and convex parts on the underbody panels; and welding the stamped underbody panels to splice the underbody in a longitudinal direction and/or a width direction, so as to make the underbody reach the determined length and width. Underbodies with various dimensions can be formed using the same stamping die, and accordingly, a die cost is saved and vehicle development time is shortened, which provides convenience of diversified body designs on the whole.

    본 발명은 언더바디 제조 방법 및 자동차 언더바디를 제공한다. 방법은 자동차 언더바디 및 언더바디 패널들의 크기들을 판별하는 단계, 언더바디 패널들을 선택하는 단계, 언더바디 패널들을 스탬핑을 위한 스탬핑 다이에 위치시켜 언더바디 패널들에 오목하고 볼록한 부분들을 생성하는 단계, 스탬프된 언더바디 패널들을 용접하여 언더바디의 길이 방향 또는 폭 방향에 붙여 언더바디가 결정된 길이 및 폭에 도달하도록 하는 단계를 포함한다. 다양한 크기들을 갖는 언더바디들은 동일한 스탬핑 다이를 이용하여 형성될 수 있으며, 따라서 다이 비용이 절감되고, 자동차 개발 시간이 감소되므로, 다각화된 바디 다자인이 용이해진다.
