| 摘 要： | 在用自动网格法做大模型试验之前，先做了一个刚体移动实验对自动网格法测试系统进行了标定。在一张纸上生成网格点，将纸固定在平移台上，再将平移台放在防震台上。平移台的移动由带有刻度的螺拴控制。网格点每移动一步，用CCD摄像机拍下网格点，用专用程序提取位移信息。通过标定，认为这套测试系统是可行的。最后讨论了影响本次精度的因素。

| Abstract: | Before model big test is made by automated grid method, measurement system is checked up by making movement test of rigid body. Firstly, gird points are made on a paper. Secondly, the paper is fixed on movement table. Finally, movement table is put on quakeproof table. Table movement is controlled by bolt with scale. When grid points are moved, they are took by CCD camera and their movement information is gained by automated grid program. Through check-up, the measurement system is practical. Finally, factors of influencing precision are discussed. |
