| 中文摘要: |
| 采用液压作动器/电静液作动器（HA/EHA）非相似余度配置的混合作动系统是未来多全电飞机作动系统的发展趋势，为解决混合作动系统能耗大、发热严重的问题，首先对构成混合作动系统的EHA进行效率分析，通过对比效率特性，提出根据不同工况自动切换至高效率通道进行工作的优化方法；分析飞机飞行空气负载四象限工况特点，以负载力F和作动筒运动速度v构成的工况网络作为切入点，提出了自适应工况与能量回收的混合作动系统工作模式，相较于传统工作模式能耗降低50%以上，并通过仿真验证该方法的有效性。 |

| The hybrid actuating system with HA/EHA dissimilar redundancy configuration is the development trend of the future multi electric aircraft actuating system. In order to solve the problem of high energy consumption and serious overheat in the hybrid actuating system, first, the efficiency analysis of HA and EHA that constitute hybrid actuation system should be made, by comparing the efficiency characteristics, an optimization method is proposed to automatically switch to a high efficiency channel according to different working conditions; Then, the operating characteristics of air flight load of four quadrant are analyzed, to load F and actuator velocity conditions constitute the V network as a starting point, proposes a hybrid energy recovery and adaptive conditions of actuator system work mode. Compared with the traditional working mode, the energy consumption is reduced by more than 50%. The effectiveness of the method can be verified by simulation. |
