摘要
加油装置是加油机的重要发展方向之一,加油接头力传感器是其自动卸荷系统消除动臂载荷实现闭环控制的重要设备,但目前国内尚无该类设备满足实际装机使用要求。通过对加油接头力传感器进行总体设计研究,解决电路与燃油通道隔离及电磁屏蔽,尽量消除俯仰与滚转测量的串扰等问题,将弹性体设计为管状结构,确定合理的应变敏感位置。在小外廓尺寸前提下实现其内径同伸缩管及加油接头的内径一致,保证加油系统结构的最优设计,并提高了测量精度。通过输出灵敏度等设计、分析与测试验证,实现了动臂载荷的安全可靠和准确测量,为该机载设备研制提供了支撑。
The refueling device is one of the important development directions of the air tanker.The force sensor of the boom nozzle is important device for the automatic load alleviation system to eliminate the boom load and realize the closed-loop control.However,at present,there is no such device in China to meet the actual need.The overall design and research of the force sensor for the boom nozzle is carried out to solve the problems of the isolation of the circuit from the fuel channels,electromagnetic shielding,and the crosstalk of pitch and roll measurement.The elastic body is designed as a tubular structure,and the reasonable strain-sensitive position is determined.Under the premise of small outline dimensions,consistence of the inner diameter of the elastic body with that of the telescoping boom and the nozzle is achieved to ensure the optimal design of the refueling system structure and improve the measurement ac⁃curacy.Through the design,analysis and test verification of the output sensitivity etc.,the safe,reliable and accurate measurement of the boom load is realized,which can provide support for the development of the refueling device.
