摘　　要：针对齿轮传动的优化设计问题,以模糊数学为基础,运用可靠性优化设计理论,将膜厚比、临界转速比纳入约束条件,考虑齿轮应力及强度的概率分布,建立了泥浆泵齿轮传动机构的模糊可靠性优化设计数学模型,并通过运用Matlab遗传算法工具箱编程求解,得出全局最优解.结果显示,齿轮传动的综合性能得到有效改善,并证明了优化方法的正确性与合理性,为齿轮传动优化设计提供了新的参考.In view of the problem of the gear transmission optimization design,based on the integration of fuzzy mathematics and reliability optimization design theory,a mathematic model of reliability optimization design of the mud-pump gear transmission mechanism was built with its stress and intensity obeyed certain probability distributions,when the film thickness ratio and critical speeds ratio ware put into constraint. The global optimization result was found by using GA toolbox in Matlab. The optimal results show that the comprehensive performance of the gear transmission is improved efficiently,and the correctness and applicability of that optimization method is proved,hence it provides a new reference for the gear transmission optimization design.
