【Abstract】 Considering the fuzzy nature of the constraints and the fuzzy factors in transmission gear designs, we present a mathematical model for fuzzy reliability optimal design for a motor driven elevating calabash reductor to satisfy the requirement of a specified degree of fuzzy reliability. A calculation example is given as well using the combination of Genetic Algorithm(GA) with Sequence Unconstrained Minimization Technology(SUMT). Compared with the traditional optimal methods, the combination of GA with SUMT can obtain a better, more effective and efficient result.更多还原
