Abstract

Due to the complexity of the planetary gear train (PGT), it is difficult to design novel configurations of power-split hybrid transmission with three planetary gear sets (PGSs) containing input-split and compound-split two modes. One of the effective solutions is to complete configuration synthesis and establish a complete database of configurations to assist in the design. For this reason, a uniform and simple digital code is proposed to represent the two-mode power-split hybrid transmission configuration, which divides the configuration into PGT and shift element (SE) two parts. The computer only needs to read the digital code to automatically complete the mode analysis, motion characteristics analysis and mechanical interference detection, which are the basis for the configuration synthesis. In addition, to improve design efficiency, while completing the configuration synthesis, the structure and motion characteristics of each configuration are stored in MySQL database, which realizes the fast reading of configuration information. Through this method of assisting configuration design, engineers can quickly search for feasible configurations according to the requirements. Therefore, this method is instructive for the design of power-split hybrid transmission configuration.

提出了一种基于数字编码的三行星齿轮组双模功率分流传动结构分析与数据库综合方法

由于行星轮系的复杂性，设计包含输入分路和复合分路两种模式的三种行星轮系的动力分路混合动力传动具有一定的难度。有效的解决方法之一是完成构型综合，建立完整的构型数据库来辅助设计。为此，提出了一种统一、简单的数字编码来表示双模功率分路混合动力传动配置，将配置分为PGT和换挡元件（SE）两部分。计算机只需要读取数字代码即可自动完成模态分析、运动特性分析和机械干扰检测，这是构型综合的基础。此外，为了提高设计效率，在完成组态综合的同时，将每个组态的结构和运动特性存储在MySQL数据库中，实现了组态信息的快速读取。通过这种辅助配置设计的方法，工程师可以根据需求快速搜索到可行的配置。因此，该方法对功率分路混合动力传动结构的设计具有指导意义。
