摘要
在结构静强度试验过程中,加载控制系统是试验载荷施加的关键控制机构,加载控制系统输出的加载数据将直接反应试验件载荷受力情况;目前MOOG加载控制系统提供的数据输出格式不具有较直观的阅读性,增加了试验人员对加载数据处理的难度;为此提出了一种基于LabVIEW的软件设计方法,对MOOG原始加载数据进行二次处理,并转换为常用的数据格式,实现加载控制通道相对误差的自动计算,并自动生成加载控制数据报告;该软件设计方法在大幅降低试验人员处理数据难度的同时缩短了试验数据处理周期;在提高了工作效率的基础上,减少了人工操作的出错率,有助于飞机结构强度试验的数据分析工作。
Loading control system is the key control mechanism in static strength test of structures.The loading data will directly reflect the loading condition of the test piece.At present,the data output format provided by MOOG loading control system is not intuitive enough to read,which increases the difficulty of data processing for the test personnel.For this reason,a software design method based on LabVIEW is proposed in this paper.The original load data of MOOG is processed twice and converted into a common data format to realize the automatic calculation of relative error of load control channel and automatically generate load control data report.The software design method greatly reduces the difficulty of data processing and shortens the period of data processing.On the basis of improving work efficiency,the error rate of manual operation is reduced,which is helpful for the data analysis of aircraft structural strength test.
