工程车辆传动轴的模糊可靠性优化设计

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

依据统计学和模糊数学理论,考虑设计参数的随机性和模糊性,将模糊可靠度作为设计变量的约束条件,建立工程车辆传动轴的模糊可靠性优化设计和数学模型,并给出实际算例。

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~ more rational to design the transmission shaft of mobile engineering vehicles by means of the optimizing design of the fuzzy reliability.
