摘　　要：基于Variable-cycle engine(VCE)模式切换的功能需求,提出一种传动切换机构(driving and switching mechanism,DSM)的通用设计方法。先利用双排行星轮系(double row planetary gear train,DRPGT)架构设计出一种具备相位和传动比同时可变特征的通用传动机构方案,再通过构型设计拓扑出功能结构相似的系列化机构方案,并采用粗糙集理论结合聚类分析法开展其类型综合与分类研究。最后分析得到一类前排为单行星轮系,后排为双行星轮系的串联传动机构方案,此类方案满足VCE模式切换工作需求,且具备紧急情况下中断动力传递的功能。研究证明:设计分析方法应用于机构类型综合与分类研究高效可靠。Based on the functional requirements of variable-cycle engine （VCE） mode switching, a universal design method for a driving and switching mechanism （DSM） is proposed. A universal DSM with a double row planetary gear train （DRPGT） is designed in which the phase and transmission ratio can be adjusted at the same time. A series of mechanism schemes with similar structures and functions are obtained by configuration design and to- pology analysis, and rough set theory is used to study the classification and type synthesis. Finally, a series DSM scheme with a DRPGT is obtained, with one planet gear in each group in the front row between the gear ring and sun gear and two outer gearing planet gears in each group in the rear row. This kind of scheme not only meets the demands of VCE mode switching, but can also interrupt the power transmission in case of emergency. Research results indicate that, the design analysis method which is applied to the classification and type synthesis of mechanism schemes is efficient and reliable.
