摘　　要：针对带传动优化过程中存在的多目标、多约束特点,采用多学科设计优化理论进行了V型带传动参数的优化设计。以中心距和皮带根数最小为同步优化目标,利用协同优化算法思想建立了两级优化数学模型,其中包括一个系统级模型和两个子系统级模型。运用iSIGHT软件对优化数学模型进行了求解,与现有文献的优化方法相比,中心距和皮带根数均有减小,可以简化结构并降低成本。计算结果表明多学科设计优化在处理多目标优化问题时有明显的优越性。According to the characteristics of multi-objective and multi-constraints exist in the optional design of belt drive,the parameters of V-belt transmission are determined based on the ideas of the multidisciplinary design optimization(MDO).To minimize the center distance and the piece number of belt synchronously,a two-level optimal model including one general model and two sub-models is constructed by virtue of collaborative optimization algorithm.Then a commercial software iSIGHT is employed to solve the two-level model.It proved to be better than those provided by the existed literature,and the center distance and the piece number of belt are reduced,which can predigest the structure and reduce cost.This fact also shows that MDO is a valuable tool for multi-objective optimal problem of machinery design.
