对国内外不同挤压—旁路比载荷的测定方法进行研究,在总结其优缺点的基础上,经过反复推敲、多次试验研究,提出一种简单、易行、比较准确的测定方法,并在铝合金试验件上、下两部分用应变测量法进行验证,效果良好。进而对复合材料结构常用的挤压—旁路比进行两种不同铺层材料结构测定试验,使所研究方法得到有效应用,测试结果可供飞机结构设计部门参考使用,试验方法可供结构连接件试验部门参考使用。
On the basis of summarizing the advantages and disadvantages of different crush-bypass specific load tests both at home and abroad, a simple, easy and accurate measurement method is proposed after repeated scrutiny and repeated experiments. In the aluminum test piece, the next two parts with strain measurement method for verification, the effect is good. Furthermore, two kinds of different lay-down test of composite materials are carried out on the common crush-by-bypass ratio of composite structure, so that the research methods can be effectively applied. The test results are available for reference to the design department of aircraft structure. Test department reference to use.
