Abstract: To support the digital assembly design function of complex product effectively,the function modules such as product assembly modeling,assembly sequence planning,and assembly path planning and analysis in digital assembly system were analyzed.The functional model for digital assembly system was proposed.In product assembly modeling module,to improve the precision and accuracy of assembly process,the digital assembly model contained tolerance modeling was put forward by considering the assembly tolerances.To reduce the complex product assembly costs,shorten the assembly time and improve the quality of assembly,a kind of open,reconfigurable,reusable and extensible integrated digital assembly system architecture based on Service-Oriented Architecture (SOA) was put forward.

Key words: digital assembly, architecture, functional structural diagram, complex product, assembly model, service-oriented architecture
