Abstract: Based on the method of arc-length parameter space, namely
mapping the initial CAD data model into the parameter space, after
adjustment, then mapping back to the physical space, preserving surface
characteristic in the process of transformation will not change the
model surface shape. The method is applied to the surface grid of
automobile body and obtains the predictive effect. The method of
arc-length parameter space provides a good solution for the surface grid
of complex geometry contour, and establishes the foundation for the
further analysis carried out.
Key words: Arc-length parameter space Automobile body Surface grid
