Based on the precedence matrix among parts in the lowest level,algorithms to detect and verify the serial sub-assembly as well as parallel sub-assembly were developed.

Meanwhile,based on the information of the function structural tree and its parts of the production,the sub-assembly was judged by dividing the assembly relation graph and matching the rule.

The research on subassembly detection in assembly sequence plan;

Facing to the difficulties in manual judging subassembly unstability that usually appears in assembly process planning,unstability discrimination and clamping scheme selection were provided to help engineers to plan the assembly process of subassembly.

The algorithm of the subassembly division is proposed according to subassembly definition and matrix expression for the assembly structural information.

Top-down Assembly Design and Simulation of Motion Based on SolidWorks;

Parts,assembly and drawings are linked each other.

The coupler assembly with finite element analysis software I-DEAS is analysed considering the interactions between the components of coupler by defining contact.

This article explains form-position tolerance link display type and link regulation in assemble form-position dimensional chain,and the way of from-position dimensinoal chain drawing paind and fits specialty calculation in assemblage.

Rely on widely applicable software platform of Solidworks,under accomplishing dimension information and centroid coordinate extracting of the each part through excel electronic form,and compiling unified XML worksheet and program group,in order to get object assemblage with the help of centroid coordinate of part which has been realized parameterization one by one.
