Abstract: Aiming at the problem that the simulation result of current virtual assembly was inauthentic caused by the deficiency of consideration on physical attribute and human factors during assembly process,an assembly navigation method by considering human factors was presented.Based on physics-based assembly simulation method,the human factors involved in the assembly process were analyzed,and the quantitative evaluation for visibility,comfort and energy consumption were obtained.According to the evaluation value of each factor,the size and direction of assembly force were calculated with Monte Carlo method.By dynamic simulation,the assembly location of parts was accomplished.The proposed method was applied to a self-developed desktop virtual assembly prototype system,and the comparative analysis showed the effectiveness of the proposed method.
