A DOE method was applied to analyze the front wheel alignment parameters of minibus herein. An optimization objective function considering the tolerance of front wheel alignment parameters' practical values and setting values under laden conditions, and the method of combining the orthogonal arrays theory with DOE method in ADAMS were put forward. The front wheel suspension system was founded based on this method, which was utilized to optimize the design of front wheel alignment parameters. The advances and validity of this method was testified by comparing the results of before and after the optimization.
