摘　　要：介绍ZYF-3型织物悬垂三维测试仪的测试原理及其误差分析。从非点光源造成的误差、抛物面误差对光线平行度的影响、光线的不平行度造成的误差等几个因素入手,分析了该仪器存在误差的几个方面。分析表明,可以通过调整两道光栅的间距和适当地减小光栅透明部分的宽度,来减小光线不平行对测试结果的影响。分析结果为织物悬垂性能测试结果的准确性提供了理论参考。The testing principle and error analysis of the ZYF23 fabric-drape three-dimensional tester is introduced in this paper. The errors that exist in non-point light source, parabolic machining, nonparallelism of light are analysed. The analysis indicates that adjusting the distance between the two gratings or reducing the width of the crystal part of grating properly is an effective way to diminish the effects that nonparallelism of light caused to the test results. The analysis also provides theroretical reference available to amend the accuracy of fabric drapability test result.
