Abstract: Minimized angular variation stage-by-stage method (MAVSM) and minimized the final angle variation method (MFAVM) were proposed based on the state space model for vehicle assembly, and compared with the direct assembly method (DAM). The results showed that the angular variation of DAM follows the Rice distribution, and increases with the stage. The MAVSM and MFAVM follow generalized extreme value distribution. MAVSM is not affected by the stage, but the mean and standard deviation of angle variation decrease with the stage and converge at 0 for MFAVM.
