At last of the paper , build the test table of the high speed bearing . test and collect the data of temperature and vibration of the bearing in high speed 本文最后通过试验研究的方法对轴承在不同转速、不同工作载荷下的工作温度和轴系振动进行了测量和分析。
Provide ddl to setup test tables and dml to provide basic data where appropriate . don ' t describe the tables and data , give me the actual creation and insert statements 提供建立表的ddl和插入数据的dml语句(这样有利于回答者建立测试的环境) ,不要老是描述数据,你干脆提供语句不就得了。
The following a java program inserts a mixed character string that contains both english and chinese characters into the description column of test table and to display the result on screen 以下java程序将一个混合字符串(包含英语和中文字符)插入test _ table的description列,并在屏幕上显示结果:
The dropping test table , high temperature test cabinet , vibration test table and impacting table , which can simulate many dynamic test of frequency of 5 60hzdisplacement and amplitude of 5 mm 100 %等多种温度条件,跌落试验台高温试验箱振动试验台冲击试验台等均有中国国营西北机械厂生产,可模拟频率5
Testing table is special equipment for inertia navigation system and inertia component ’ s research , which can be used to examine or calibrate inertia navigation system or study the error models 测试转台是惯性导航系统和惯性元件研制过程中必须的重要设备,它可以用来进行惯导系统和元件的检定、标定以及建立误差模型。
According to the character of this three - axis simulation and testing table , describes the fully digital control scheme of this table in details and proves the applicability and effectiveness of the scheme 针对该三轴仿真、测试转台的具体特点,详细阐述了该转台所采用的全数字控制方案,说明了该方案的可行性和有效性。
Then the author experimented them . from the simulate and experiment i can see , the static precision of three - axes of testing table can reach the request , the controlling maneuver which the 对常用测试方法和工作原理进行分析,确定用光学自准直仪测试转台回转精度和轴系垂直度的测试方法,并进行实际测试,完成数据的处理和精度分析。
