‘壹’ 转台轴承适用范围有哪些

主要适用于高精度数控转台、分度头、军工雷达、航空、航天、工业机器人及测量和试验中要求精度高的领域。

‘贰’ 二维转台的研制高精度伺服转台系统的背景和意义

在军事上,雷达天线的自动瞄准跟踪控制,高射炮,战术导弹发射架的瞄准运动控制,坦克,军舰的炮塔运动控制等都是基于对二维数控转台的运动控制,所以对其进行研究有重要的现实意义。所以说转台性能的优劣直接关系到仿真试验的可靠性和置信度,是保证航空航天型号产品及武器系统精度和性能的基础,在航空航天工业和国防建设的发展中具有重要的意义。转台也是机电实验室中常用的实验设备,对提高实验室科技水平有着重要的意义。
在现代战争中,电子战所发挥的作用越来越重要,如两次海湾战争,美国为首的多国部队充分发挥了电子对抗设备的综合效能,使其获得了战争的巨大成功。海湾战争的大量生动的事实,使我看到了现代战争的含义和电子战重要性。我国周边地区局势不容乐观,特别是维护我国领土的完整性,对有分裂趋向的势力保持有足够的威慑力,在现代战争中,发展电子对抗系统是非常必要的。
过去,在电子战的领域中,人们只注意侦察、预警设备和各种干扰手段的发展,往往忽略了如何将它们有机地结合起来发挥更有效的作用。将这些设备有机地结合起来,必须要有高性能的控制平台,这就需要对雷达伺服控制系统的跟踪、定位精度有更高的要求,研制高性能的伺服控制系统对国防事业有着重要的作用。
国内相关单位对转台伺服研究主要集中在以下三个方面:
(1)对用于惯导测试和运动仿真的转台研究,用于此目的伺服转台的技术指标高,如中航303所研制的单轴,双轴,三轴惯导测试和运动仿真设备的伺服转台系统,它们典型的技术指标为角度精度是±2~±30,其中TDC-2型陀螺动态参数测试系统的转台精度在±2,STS-210P型单自由度目标视线运动仿真器,另外如航天一院102所研制的DSW-O1单轴速率位置转台的性能指标,位置分辨率为0.005,中船6354所的ST-160,ST-380型单轴位置转台。
(2)对数控机床的伺服转台的研制。
(3)对雷达伺服转台的研究,如航天二院203所研制的计算机控制的转台装置,2000年东南大学科技成果《EMC自动测试用转台和天线塔》,北京友信科技集团的URT-L-O1雷达仿真转台。在雷达转台伺服系统中,高精度的产品还比较少,为了加快雷达伺服转台的技术水平,适应国防技术的需要,很有必要研究高精度的雷达转台伺服系统。

‘柒’ 二维转台的国内外转台的发展状况

转台是一种复杂的集光机电一体的现代化设备,在航空、航天领域中进行半实物仿真和测试,在飞行器的研制中起着关键的作用,它能够模拟飞行器的各种姿态角运动,复现其运动时的各种动力学特性,对飞行器的制导系统、控制系统以及相应器件的性能进行反复测试,获得充分的试验数据,并根据数据对系统进行重新设计和改进,达到飞行器总体设计的性能指标要求。
在国际上,由于惯性制导技术受到世界上技术先进国家和发展中国家的普遍重视,所以美国、俄罗斯、英国、法国、瑞士、中国、印度等国都投入了大量的资金和人力从事转台的研制。其中,美国的转台研究一直处于世界领先水平,其次,德国、英国、法国和瑞士等国研制的转台也具有一定代表性,性能和质量仅次于美国。
世界上的第一台转台是1945年由美国麻省理工学院仪表实验室(MITInstrumentation lab)研制成功的,定为A型转台,采用普通滚珠轴承,用交流力矩电机驱动,角位置测量元件采用滚珠与微动开关,由于采用的元件精度比较低,加上没有经验可以借鉴,该转台存在许多缺点,精度也只能达到角分级,实际上没有投入使用。随后,美国的欧思一伊利诺斯公司的菲克(Fecker)系统分公司又研制出了T-800型伺服转台,它标志着美国的转台设计己经达到了一个新水平。六十年代开始对转台的重要部件如轴承、驱动马达和监测元件进行了系统的改进,研制成功了专用于转台的空气轴承和液压轴承,大调速比、高精度的液压马达和高分辨率的检测元件,把转台的技术水平推向了一个新台阶。同时诞生了一些专业生产转台的公司,如美国的CGC(Contraves-Goerz Corporation现己改组)公司、Carco公司(Carco Electronics,现已并入欧洲的Acutronic公司)、德国的MBB公司等。
我国的转台研制虽然比发达国家起步晚,但这些年来也取得了一定的成就,特别是近几年来,转台的研制得到了很大的发展。目前,国内也有很多研究机构和高校在从事转台的研究与开发,例如哈尔滨工业大学、中航303所、中船6354所、南京航空航天大学等。我国在20世纪60年代自主研发和制造了第一台液压飞行仿真转台,为我国早期飞行器控制和制导系统的发展做出了巨大的贡献。进入80年代后,我国将数字控制引入到了转台控制中,用软件实现了复杂控制规律,参数调整也比模拟控制器方便,将我国的转台研究开发带入了一个新的时代。1990年,中航303所研制成功了SGT 1型三轴捷联惯导测试转台,这是我国第一台计算机控制的高精度三轴惯导测试台。进入90年代以来,转台的研制进入了数字和模拟的要求也越来越高,这就对转台的设计和整定提出了更高的要求。
国内也研制了许多不同形式不同用途的精密伺服转台,从国内产品上看在相同结构刚度的前提下国内产品做的较重,载荷较小,这给小型化、机动性带来很大困难。由于国外相关产品进口始终处于严控状态。因此只能立足于自己研制。而自己研制需要解决的问题是如何在结构上做到轻质量高刚度、高精度。

‘玖’ 数控机床精度检验包括哪些内容,采用什么工具检测

数控机床精度检测内容主要包括数控机床的几何精度、定位精度和切削精度。
(1)数控机床几何精度的检测
数控机床的几何精度检验,又称静态精度检验,摇臂钻床是综合反映机床关键零部件经组装后的综合几何形状误差。
目前,检测机床几何精度的常用检测工具有精密水平仪、精密方箱、直角尺、平尺、平行光管、千分表、测微仪、高精度检验棒及刚性好的千分表杆等。检测工具的精度必须比所测的几何精度高一个等级,否则测量的结果将是不可信的。
(2)定位精度的检验
数控机床定位精度,数控机床是指机床各坐标轴在数控装置控制下运动所能达到的位置精度。
测量直线运动的检测工具有:测微仪和成组块规、标准刻度尺、光学读数显微镜和双频激光干涉仪等。回转运动检测工具有:360‟齿精确分度的标准转台或角度多面体、高精度圆光栅及平行光管等。
(3)切削精度的检验
机床的切削精度,又称动态精度,是一项综合精度,它不仅反映了机床的几何精度和定位精度,同时还包括了试件的材料、环境温度、数控机床刀具性能以及切削条件等各种因素造成的误差和计量误差。切削精度检验可分单项加工精度检验和加工一个标准的综合性试件精度检验两种。被切削加工试件的材料除特殊要求外,一般都采用一级铸铁,使用硬质合金刀具按标准的切削用量切削。
