摘要
采用分级优化技术对NGW型行星齿轮传动的参数进行选取,构建其二级优化的数学模型,包括以模数、齿数和齿宽为设计变量,体积最小为优化目标的第一级优化模型,以及以提高啮合性能为目标的选取变位系数的二级优化模型.使其在保证预定承载能力的前提下,达到整体体积最小和啮合性能最佳的双重优化目的,并通过实例验证了该优化方法的有效性.
By using gradual optimizing designing to choose the coefficient of NGW plant transmission, a two level optimi- zation mathematical model was constructed. The modulus, tooth number and tooth width were the designing vari- ables. While minimum volume was the optimization objective of the first level of the optimization model, the selection of variable coefficient to improve the meshing performance was the target of the second level of the optimization model. Opti- mization was thus realized for volume and the capability of meshing under the carrying capacity. The mathematical model was established and its effectiveness was proved with examples.
