摘要
飞机地面结构强度试验,多采用液压加载的方式,为保证试验安全、高效完成,控制设备与加载设备、测量设备之间需要多种辅助装置进行信号的转化匹配,比如子站控制、应急信号汇总、测量触发等。针对现有辅助装置的多样复杂问题,采用CPLD设计了一种高度集成的智能辅助装置,完成多型号、多试验同时进行时的控制设备与加载设备、测量设备之间的协调任务。试验结果表明,该辅助装置高效的完成了控制与加载、测量之间的桥梁连接作用,且可根据需要编程实现功能的变化,简化了繁琐的中间环节,提高了设备利用率、试验能力以及效率,保证飞机结构试验的安全性、可靠性。
The aircraft ground structure strength test mostly adopts the hydraulic loading method.In order to ensure the safe and efficient completion of the test,a variety of auxiliary devices are required for signal conversion and matching between the control equipment and the loading equipment,measuring equipment,such as substation control,emergency signal summary,and measurement trigger,etc.Aiming at the various complicated problems of the existing auxiliary devices,CPLD is used in this paper to design a highly integrated intelligent auxiliary device to complete the coordination task between the control device and the loading device when multiple models and multiple tests are performed simultaneously.
