And virtual assemblies of the Experimental Advanced Superconducting Tokomak device (EAST) and the fusion-driven sub-critical system (FDS-I) are successfully simulated on FVAS.
The assembly tolerance analysis and optimization method based on digital product design model is put forward according to the analysis of digital-ization preassembly method.
According to the concept of context process problem space,. the concept of Directed Assembly Relationship Graph(DARG) was put forward. The isomorph of DARG was defined.
This paper makes a meshing analysis about the spiroid gearing. Using the method of equivalent worm gearing, the assembly condition of Archimedes spiroid gears has been obtained.
