In order to solve the problem of combined explosion in disassembly sequence modeling, a theory of general axle is proposed based on the relationship between containing and being contained of hole-shaft constructs in mechanical system. Principles are then employed for decomposing a disassembly system into several leveled and nested general axle units. All general axle units have the unified name and form of data management, which is consistent to the geometrical part of disassembly knowledge-base. Engineering attributes added as another part of information data unit to improve the practicability of the disassembly sequence planning. Furthermore, a disassembly Petri net based on knowledge-base is built and a case is used to explain that the new model are more saving calculation space and tally with the actual situation.
