Abstract
The three major American automobile companies have promoted and applied the statistical quality management method of “2 mm” engineering to automobile enterprises all over the world in the 1990s. Under the influence of this view, the concept of function dimension is often applied to the manufacturing process in the early days. With the continuous improvement of consumer’s requirements on automobile appearance gap and flush, the welded white body’s structure and assembly technology become more and more complex. Under this background, the design and application of function dimensions on BIW are very important. This paper gives the design intention and design method of function dimensions by analyzing the body structure and assembly scheme of the vehicle’s front area, which is the most difficult area of vehicle’s exterior DTS. Finally, using the virtual assembly tolerance analysis software analysis verifies the correctness of the design tolerance of the above function dimensions. To some extent, it solves the practical application problem of function dimension’s design in vehicle research and development.
