Abstract: In a virtual assembly process simulation, it is difficult to simulate the real assembly process completely due to the imperfection of haptic and force feedback. To solve this problem, a novel assembly process simulation method is proposed in this paper. Firstly, the rough and exact placement stages were divided according to the actual assembly process. Then, a series of judgment rules were formulated to determine their assembly completeness according to the differences of geometric features and assembly methods of different parts. Meanwhile, to let users feel the constraint effect of contacts on part motion in the virtual environment without force feedback, a heuristic analysis method is introduced. The results show that the proposed method can better reflect the uncertainty of human's actual assembly operation compared with the method based on geometric constraints, and it can better meet the needs of assembly analysis of mechanical products.
