英文摘要:

      The operational feature and the theory of lever amplification force standard machine with one traveling weight are presented.The key technology of the standard machine controlled with precision is the accuracy of the weight's displacement and the horizontal state of lever.Firstly,it uses the straight-line displacement of precision machine tool.Secondly,it establishes relevant control methods and systems.Finally,it puts forward and adopts the method that applying plane figure composed of operational principle and structure as the interface part,and showing the change of assembly unit in the picture corresponding to exact working condition of the machine.The experiment proves that this monitoring control method is testified as effective,straightforward,vivid and reliable,and furthermore,it can makes the machine return zero position automatically and operate easily,precisely and efficiently as well.
