Abstract: According to the facts of researches on disassembly
sequence, the mathematical model of hierarchical probabilistic fuzzy
cognitive map and a method to generate disassembly sequence in the whole
disassembly using hierarchical probabilistic fuzzy cognitive map are
proposed. The method can extract information from assembly graph, such
as disassembly stability and interference decision, and express
disassembly model easily when the number of parts is too much or the
relations among the parts are too complicated. So this method
effectively makes up the deficiency of other methods. Referring flywheel
accessory as study case at last, a system is got by using VC++ 6.0 to
develop the three-dimension software UG. This system can extract the
mating information from the three-dimension model of the products to
direct the expert to establish the hierarchical probabilistic fuzzy
cognitive map, generate disassembly sequence, and demonstrate the
disassembly process dynamically, and check the disassembly stability,
interference problem and correctness of disassembly sequence. So it
shows that this method has features such as simpleness, robustness and
practicality.
