Abstract: The planetary row hybrid powertrain is widely utilized because of its highly efficient planetary row. For the planetary row hybrid powertrain system, a molecule-like topology design method for hybrid powertrain based on pattern screening is proposed, which not only effectively reduces the complexity during design, but also eliminates the powertrain configuration with duplicated functions. Furthermore, to prevent power cycling issues that reduce transmission efficiency in the configurations generated by this topology design method, a universal screening principle is introduced and incorporated into the screening process. Under this principle, the fuel economy of the optimized configurations improves by 5.56%. Through this topology design method, 173 hybrid systems with perfect performance and simple structures are finally obtained.

摘要： 行星排式混合动力系统因其具有高效率的行星排得到广泛运用。针对行星排式混合动力系统，提出基于模式筛选的混合动力系统类分子拓扑设计方法，该方法不但能有效的降低设计时的复杂度，还能摒弃功能重复的动力系统构型。并且，为避免此拓扑设计方法的构型中出现降低传动效率的功率循环问题，提出了一种通用的筛选原则，并增加到此拓扑设计方法的筛选流程中。在该筛选原则下，其优化构型的燃油经济性提高了5.56%。通过该拓扑设计方法，最终得到性能完善、结构简单的173 种混合动力系统。
