Abstract: Aiming at the possible problems of combinatorial explosion and physical connectivity design defects in complex mechanical products assembly planning,an automatic identification and modification algorithm for assembly physical connectivity design defects based on immune mechanism was proposed.To solve automatic identification and stable connection problems of sub-assembly,the connection matrix of assembly physical constraint was redefined,whose encoding features was used with vaccination strategies of immune system to draw identification operator and modification vaccine of design defect and identification vaccine and adjustment vaccine of sub-assembly.Through integrating above modules,an immune identification and modification algorithm for assembly physical connectivity design defects was established.A decelerator assembly example contained sub-assembly structure was taken as an example to verify the effectiveness and correctness of proposed algorithm.
