新型飞控驾驶舱操纵机构故障状态建模与分析

某电传民机驾驶舱操纵机构采用超控杆的连接形式,该种机构重量轻、维修性好,但是故障模式具有多样性和复杂性,针对这一问题,研究其驾驶杆操纵机构的原理和物理特性,对其正常模式和单侧驾驶杆卡阻故障模式进行建模,并对各故障模式进行分析和杆力特性品质评估,结果表明:该种操纵机构在故障模式下的杆力特性品质是可以接受的。

Modeling and Analysis about a Fault State of a New Cockpit Control Mechanism

Override rod linkage form is adopted by the cockpit control units of a certain type of fly-by-wire civil aircraft, and it brings some profits on the weight and maintainability while the problems it resulted in are the failure mode becomes diverse and complicated. For the problem, this paper does a research on the working principle and physical characteristics of the cockpit control units, through modeling and simulation on its normal mode and failure mode, and finally gives an analysis and evaluation for the column force quality of each failure mode. The simulation results reveal the column force quality of each failure mode is acceptable.
