摘要

针对航空发动机智能化发展对多功率路径传动的需求,本文对变功率路径附件传动链结构设计与控制方法进行了研究。提出了基于狗牙常闭式电磁离合器的可变功率路径传动链创新结构,通过电磁离合器结合与分离实现功率路径切换;构建了机电磁多场耦合的传动链系统动力学模型,实现了功率路径切换过程精准仿真;制定了功率路径切换控制策略,并开展了台架试验验证。结果表明,该设计实现了2条功率路径,满足主发动机工作模式、空中安全模式、地面维护模式和主发动机启动模式4种工作模式;仿真显示,空中安全模式下主发动机转速降至10%和64%时,功率路径切换时间分别为0.1285 s和0.3000 s;台架试验表明,功率路径切换时间不超过0.35 s,电磁离合器结合时能在转速11.7 krpm下稳定传递扭矩,分离时在8.4 krpm的转速差下稳定保持3900 s以上。研究验证了可变功率路径传动链结构可靠性和控制方法有效性,为航空发动机附件传动系统智能化发展提供了技术支撑。

Abstract

To address the demand for multi-power path transmission in the intelligent development of aero-engines, the structural design and control method of an accessory gearbox with variable power paths are investigated. An innovative structure based on a normally-closed electromagnetic dog clutch is designed, where power path switching is achieved through clutch engagement and disengagement; A dynamic model of the transmission chain system with electromechanical and electromagnetic multi-field coupling is constructed, enabling precise simulation of the power-path switching process; A power path switching control strategy is formulated, and bench tests are conducted for verification. The results indicate that the design realizes two power paths and four working modes: main engine operation mode, air safety mode, ground maintenance mode, and main-engine startup mode. Simulations show that under air safety mode, when the main engine speed drops to 10% and 64%, the power path switching times are 0.1285 s and 0.3000 s, respectively. Bench tests demonstrate that the power path switching time does not exceed 0.35 s; the electromagnetic clutch can stably transmit torque at 11.7 krpm in the engaged state, and remain stably disengaged for over 3900 s with a speed difference of 8.4 krpm between both ends. The study validates the structural reliability and control method effectiveness of the variable power path gearbox, providing technical support for the intelligent development of aero-engine accessory drive systems.
