| 中文摘要: |
| 针对国家标准压缩剪切夹具测试夹多种层结构材料的剪切性能时,需要多个夹具,且夹具制作成本高的不足,对其进行了改进:将与试样粘合的加载板改为组合式结构,这样可以制作多组样品粘合板,测试时只需要组装即可,大大降低了夹具制作成本,提高了试验效率,而且样品准备制作更加方便。 通过试验对改进的组合压缩剪切夹具与标准夹具进行了对比验证,结果表明组合夹具与标准夹具相比所得数据稍有差别,但压缩剪切载荷最大值差别在依10% 以内,提高了夹具的制作精度后,组合夹具完全可以代替标准夹具。 |
| 英文摘要: |
| Testing compression shear properties of sandwich structure by China national standard fixture, we need multiple fixtures when a number of samples are tested, and fixture cost is expensive and inconvenient. We improved the fixture for these defects. The loading plate bonded with sample was changed to assembly structure to make combination compression shear fixture (CCFS). Multiple sets adhesive plate was manufactured cheaply, reducing the production cost of fixture, improving testing efficiency and sample preparation. Contrast verification results by test between standard fixture and CCFS showed that compared with standard fixture, the data obtained by CCFS are slightly different, and maximum value difference of compression load shear is within 10% . It was concluded that CCFS can substitute standard fixture completely after improving manufacture accuracy. |
