Abstract:

The COM is characterized by some computational difficulties in its application. The sources of the computational difficulties were analyzed and several alleviators were reviewed. An improved COM was suggested by modifying the quadratic compatibility in the system level, might be called as the COM based on the dynamic constraints in the system level. The new method updated the constraints in the system level, can avoid the computational difficulties from the system level constraints of the original COM. The improved COM was used to the optimal design of a gear reducer. The results showed that the improved COM is characterized by high robustness, reliability and anvergence speed.

Key words: vehicle engineering, multidisciplinary design optimization, collaborative optimization method(COM), dynamic constraint
