Study on Assembly Design Method Based Digital Mock-Up

The essentiality of assembly assessment and assembly optimization in design stage is analyzed, and the existent problems of conventional assembly design method are illuminated. ADMDMU (Assembly Design Method based Digital Mock-Up) is illuminated, and the process of ADMDMU established, and the ADMDMU architecture is given out. The key techniques of ADMDMU are analyzed, and include assembly design based KBE (Knowledge Based Engineering) and virtual assembly based physically attribute. According to physical attribute, physically based modeling, visual object movement control, force simulation method and assembly sequence planning method are emphatically illuminated. Assembly design system based DMU is established in foundation of ADMDMU.
