【Abstract】 A motor-linkage mechanism system with links fabricated from three-dimensional braided composite materials is taken as the object of study.By the theory of fuzzy optimum,the mathematical model is established by means of the damping of a link as objective function,the parameters of the fibrous structure of the composite materials and the geometric dimensional of the cross section of the composite structure as design variables.According to the 3-dimentional microstructure characters of three-dimensional braided composite materials and the effects of the motor on the dynamic responses of the system,the optimum design of the system is done on the basis of the mathematical model.The method of the fuzzy optimum is verified by analyzing an example.更多还原
