摘　　要：飞机驾驶杆的杆力和杆位移测试校准在航空测控研究领域具有十分重要的意义,提出了一种针对某型歼击机驾驶杆力和位移测量的原位检测校准方法。基于VC++2010开发环境和工具,利用虚拟仪器技术,将驾驶杆的力和位移传感器信号,通过硬件系统进行信号调理,利用PCI数据采集卡进行数据采集;系统软件将采集到的各信号数据进行分析,最后以实时图形显示出杆力和杆位移的动态数据范围;通过最小二乘法曲线拟合来进一步提高解调电路的线性度,进而提高系统的检测精度。理论分析与数值试验验证了方法的有效性。This paper proposed a force and shift-length detection method for a certain type fighter airplane control stick.Aimed at the airplane control stick force and shift-length LVDT signals,a hardware who capture these signals was founded via signal conditioning circuit and PCI data collecting card based on virtual instrument technology;a software who analyze the collected signal data was founded based on VC＋＋2010,it can display the dynamic data range of stick force and stick shift-length via real-time curves;linearity of signal conditioning circuit was improved via Least Square Curve Fitting,and then detection precision of system was improved too.Theoretical analysis and experiment results show that the proposed method is effective for stick force and shift-length detection.
