摘要
在全尺寸飞机结构试验中,由于加载误差、安装误差、计算误差、扣重误差及飞机的变形等因素影响,约束点载荷反馈总是存在误差。在工程实施中,这种误差不可避免。本文分析了引起约束点载荷误差的原因,提出了解决措施,并在试验中得到验证。
There are constraint point load errors in full-scale structure tests due to loading,assembling,calculation,weight deduction,etc.These errors are unavoidable in project process.The causes are analyzed in this article,and a method is proposed,which has been proved in test.
