Fuzzy Reliability Optimum Design of the Transmission Shaft of Mobile Engineering Vehicles

According to the theory of statistics and fuzzy math, as well as with regard to the changeability and fuzziness of the designing parameters, the degree of the fuzzy reliability is made as the restricting condition for the designing randomicity. Following this condition, the optimizing design and mathematics model of the fuzzy reliability of the transmission shaft of mobile engineering behicles are established. Actual calculating models are also illustrated,The results of these models have shown that it's more rational to design the transmission shaft of mobile engineering vehicles by means of the optimizing design of the fuzzy reliability.
