中文摘要：
阵面薄膜上的褶皱会显著影响航天器性能,褶皱控制也是薄膜航天器研发的难点。本文采用白光扫描技术,测试了一个正方形薄膜阵面结构在纯剪切作用下的褶皱特性。测试结果显示,随着剪切力的增大,结构膜面褶皱数增加,褶皱幅度增大,膜面平整度降低。随着膜面预应力的增大,膜面上的褶皱数略有增大,褶皱幅度有所减小,膜面平整度有所提高。测试结果还显示,膜面上粘结缝的存在、以及粘结缝与剪切力间的方位关系对膜面褶皱有复杂的影响。论文所得结论对薄膜阵面结构设计研发具有参考价值。
英文摘要：
The presence of wrinkle in film array may significantly influence the performance of aerospace craft. Wrinkling control is thus difficulty to develop membrane aerospace structure. Whitejlight scanning technology was used to test the wrinkle characteristics of a square planar film reflectjarray subjected to the action of a pure shear force. Test results show that as shear force increases, the wrinkle quantity in the membrane increases, the amplitude of the wrinkles also increases, and the flatness of the membrane surface decreases. With the pre-jstress in the membrane increasing, the wrinkle quantity increases, but the wrinkle amplitude drops. The flatness of the membrane surface increases a little. Results also show that the existence of glue seam on membrane, the direction of seam with respect to the shear make the wrinkling more complex. Above results are valuable in the design of space planar film reflect-jarray structure.
