摘　　要：A control and test system of a landing gear drop test rig is developed considering the drop test specifica- tions for the ＂Seagull 300＂ multi-functional amphibious airplane. In order to realize the automation of drop test process, a servo system is proposed and programmable logic controller（PLC） technology is used. Several key technologies for measuring the horizontal load, the vertical load and the transient rotational speed are studied. According to the requirements of CCAR-23-R3, the drop test of landing gears of the ＂Seagull 300＂ airplane is accomplished. Test results show that the system has a high accuracy of data collection. The system is stable and reliable. The drop test satisfies the requirements of the drop test specifications and the results can be used as the certification of airworthiness for this kind of airplane.针对"海鸥300"飞机起落架落震试验的技术要求,研制了起落架落震试验测控系统。提出飞机起落架落震试验电液伺服系统的设计方案,采用可编程式逻辑控制器(PLC)技术实现了试验过程的自动化,解决了起落架落震试验机轮水平载荷、垂直载荷、机轮转速等测量技术难点。根据CCAR-23-R3要求,完成了"海鸥300"起落架落震试验。结果表明:试验系统工作稳定可靠,数据采集精度高,符合"海鸥300"飞机起落架试验技术要求,可作为其飞机适航取证的依据。
