转台

Turn-table is one of the devices which are used to simulate aerocraft's performance on the ground .

引言三轴飞行模拟转台是飞行器控制系统地面半实物仿真设备之一，属于复杂的机电系统，它存在很多不利于系统性能提高的因素，诸如电路参数的漂移、轴系间的力矩耦合、负载变化等，这些都容易引起参数时变。

A method for measuring the size of the dispersed spot of star sensor optical lens is presented. A measurement system consisting of a collimator, a rotary table and a CCD cameral was implemented to measure dispersed spot. After a image is acquired, a method of bibubic interpolation pixel subdivision is used to pick up the gray value of the image, and the size of dispersed spot is calculated by Rayleigh criterion.

提出了一种星敏感器光学系统弥散斑尺寸的测试方法，主要是利用平行光管、转台和CCD显微摄像系统组成弥散斑测量系统，采集图像后，采用双三次插值像元细分，提取图像中灰度值，依据瑞利判据计算弥散斑尺寸。

Drive a vehicle of 1 foreword 125/32t is my factory the crucial equipment of molten steel of a swing, main task is seasonable transmitting; of stage of packets of Lian Zhu is big circumgyrate smoothly is the most crucial one annulus on steel-making production catenary, once have an accident, can suspend steel-making production, bring about blast furnace even cease wind, of this equipment move smoothly, very important.

梗概： 1引言125/32t行车是我厂一台吊运钢水的关键设备，主要任务是及时将转炉出来的钢水平安、平稳地转送到连铸大包回转台；是炼钢生产链上最关键的一环，一旦出事，会中断炼钢生产，甚至导致高炉的休风，这台设备的平稳运行，非常重要。

The design of SZT-1 gyrometer test table and the realization for its working at the low temperature are introduced.

介绍了SZT-1型单轴转台的设计及低温环境下正常工作的实现。

This is the vintage 1984 Marantz turntable with Shure V15-III cartridge and the Proton DP1200 amplifier.

When the turn-table slewed, the hydraulic motor transmitted power output which enabled pinions on the output shaft to revolve.

进行回转时，液压马达输出动力，通过回转减速器减速后带动输出轴上的小齿轮旋转，小齿轮与回转支承的齿圈啮合，由于回转支承的齿圈与车架刚性连接，因而回转减速器带动与之相连的转台回转。

This turnable can be rotated in its own plane about its axis A. and is mounted on gimbals within a ring.

此内转台可在其自身平面内绕其轴线 A转动，并装在一个位于圆环里面的常平架上。

The silhouette of object on the turnable stage has been observed from multiple views through rotating. A bright background has been used to improve the contrast of images. An acquiring and processing system has been built. The 3D reconstruction algorithm has been studied based on Shape from Silhouette, and a 3D octree volume element structure model has been achieved through refining. The data will be used in 3D model repairing of laser scanning method.

本文采用单个固定CCD摄像机与转台相配合的方式，实现对物体轮廓图像的多角度采集，并使用背景照明来增加轮廓的清晰度，建立了一套自动的多视角轮廓3D测量系统，通过逐级细化的方式获得物体八叉树体元结构的三维模型，用于激光扫描法的数据修补。
