摘要
在航空结构强度试验中通常采用的试验方法有胶布带、拉压垫及卡板加载方式。对于一些结构和试验有特殊性要求的项目,应用传统加载方式难以满足试验要求或存在较大试验实施风险。真空吸盘加载技术的发明及应用满足了某些试验的特殊要求,弥补了传统加载方式的某些不足。介绍了真空吸盘加载技术在EC175/Z15平尾疲劳试验中的研究与应用,对真空吸盘加载技术的系统构成、设计和试验实施过程中的相关问题进行了分析,应用实践证明真空吸盘加载技术具有安装实施方便、可靠、高效、安全,且具有无损检测便利性。
Due to particularity of structure or requirements in aerostat strength tests. This paper aims to introduce a new loading method that makes up shortcomings of the routine loading techniques with canvas-pad, pul-pressure pad and lock-board. This method in our study is known as vacuum pad loading technique and we make a general instruction to this new technique through its application in EC175/Z15 horizontal stabilizer fatigue test. The test results indicated that vacuum pad loading technique has convenience during instalation as wel as reliability, high efifciency and security. In addition it is propitious to perform NDT.
