提出了一种三冗余传动系统设计方案，采用三组动力单元并行输入并互为备份，通过机械式复合轮系传动系统实现对各输入轴运动和动力的传动和耦合，保障系统在部分输入单元发生故障时自动完成切换，维持连续稳定的动力输出。对传动方案进行了深入的研究，给出了系统的结构布局方案，导出了为达到三路传动等效作用需满足的配齿关系。基于多学科设计优化方法建立了三冗余传动系统的优化模型，将其划分为差动轮系和定轴轮系两个并行子系统，采用基于离散变量的多学科变量耦合优化方法进行优化求解，得到满足配齿关系、强度要求和动力学要求的最优设计方案。

A design scheme of triple-redundancy transmission systems was presented in which three groups of power units parallel input and backup each other. A compound gear train transmission system coupling with input movement and power makes sure continu-ous power output by automatically switching to another mode while part of the input unit fails. Based on the analysis of the design scheme, a structure design scheme was introduced, and the matching relationship of gear teeth was derived to meet the requirement of transmission ratio. Then a multidisciplinary design optimization model of the triple-redundancy transmission system was established, in which the system is discomposed into two subsystems: differential gear train and fixed axis gear train. The multidisciplinary variable couple design optimization method of discrete variables was used in the optimal design of the triple-redundancy transmission system and the optimal comprehensive scheme was obtained which meets the matching relationship of gear teeth, strength requirements and kinetic requirements.
