一、前言本系统是根据我所承担飞机结构疲劳试验的繁重性而研制的。从设计安装到现场调试完成,用了不到一年的时间。经所技术质量处认可,分别正式在运七飞机操纵系统和运七飞机43框摇臂支架进行疲劳试验,圆满地完成了试验任务。二、系统的原理、组成及技术性能1.PC机控制的自动加载系统的原理PC机控制的自动加载系统是一个数模混合控制形式的加载系统。它依靠计算机的高速运算和逻辑判断功能,执行控制软件产生疲劳试验所需的载荷谱信
I. Preface The system was developed based on the arduousness of fatigue tests carried out on the aircraft structure that I undertake. It took less than a year to complete the design and installation to the on-site commissioning. Approved by the Technical Quality Department, the fatigue test was carried out on the rocker bracket of the 43-frame rocker arm of the seven aircraft operating system and the Yun-7 aircraft, respectively, and the test task was satisfactorily completed. Second, the system principle, composition and technical performance 1. PC-controlled automatic loading system principle PC-controlled automatic loading system is a digital-analog hybrid control of the loading system. It relies on the computer’s high-speed computing and logic to determine the function of the implementation of control software fatigue test required load spectrum letter
