一、问题的提出 从1972年开始,我们先后研制了五点协调加载机、十点协调加载机和TRS—80微机控制协调加载系统。这三个系统都只有模出部分,没有模入部分,因而只能实现小闭环控制。小闭环控制虽然解决了自动加载的问题,但是仍然不能采集实际载荷数值。要采集实际载荷就必须有模入部分。小闭环控制系统的实际载荷采集要靠其它二次仪表,载荷的调整也要靠人工实现。这种协调加载控制机使用不大方便,也不能满足复杂的程序载荷谱和随机载荷谱的要求。为了满足运七起落架疲劳试验的要求,我们研制了一套YEE8100微机控制协调加载系统。该系统是在TRS—80和IBMPC微机控制协调加载机的基础上,采用国内一些先进技
First, the issue raised Since 1972, we have developed a five-point coordinator loader, ten-point coordinating loader and TRS-80 computer-controlled coordinated loading system. These three systems are only part of the mold, there is no part of the mold, which can only achieve small closed-loop control. Small closed-loop control solves the problem of automatic loading, but still can not collect the actual load value. To collect the actual load must have modeled part. Small closed-loop control system to collect the actual load depends on other secondary instruments, load adjustment also depends on the manual. This kind of coordinated loading control machine is not easy to use and can not meet the requirements of complex program load spectrum and random load spectrum. In order to meet the requirements of Yun-7 landing gear fatigue test, we developed a set of YEE8100 computer-controlled coordinated loading system. The system is based on TRS-80 and IBMPC computer-controlled coordination loader, using some advanced technology
