| Aircraft control system primarily includes the driving rod and the pedals. Atpresent, the domestic aircraft control system mechanical properties test mainly adopt thetraditional method of manual testing instrument. Testing mainly relies on the operatingpersonnel’s experience, which need more people in the process, combined with theincreasingly subjective factors effect, beyond error range, low efficiency, may leading tothe test result appears unscientific. Also there is less possibility to get real-timemeasurement curve, and this approach won’t guarantee the product quality when testing.Thus, for the driving rod and pedals evaluation scientificly and accurately, this systemuses LabVIEW2012software platform, with such advanced ability as measurement,display，analysis and log data, which can realize function as test result automaticjudgment, alarm, history data playback and so on. At the same time the software fullymeet the demand of the man-machine interaction, thus operators can detect conveniently,hence, whether the plane control system mechanical properties is in accordance with thedesign specification requirements.This issue specifically focus on an aircraft control system mechanical propertiestest software design. Firstly, it introduces the technical indexes, hardware compositionand the underlying drivers about this system, and write the data acquisition modulebased on these parameters. Secondly, it introduces the data processing technology,software engineering ideas and multitasking, multithreaded programming theory in thissoftware. Then, it presents the main interface and function in detail about themechanical properties of aircraft control system test software, mostly includeslongitudinal calibration institutions detection, electrical property test, static test,dynamic test, the switch of the driving rod test. This software can implement thereal-time data acquisition, displaying, analysis, reporting generation, and other functions.Finally, this paper introduces the auxiliary functions of the software for man-machineinteraction, including user login, account switches, experimental record to fill in, set upthe interface, historical data playback, etc.Through the actual use of the plane, which shows that the software can accuratelymeasure the aircraft control system neutral balancing limit, polarity, stroke, dampingratio, dead zone data voltage noncutting stroke, etc. And it satisfies the various of technical indicators and design requirements. |
