一、概述随着国内机床动态试验的普遍开展,电磁激振器越来越广泛地被采用。 DJ型电磁激振器测力表就是在电磁激振器的基础上,根据使用要求而研制的。它与电磁激振器连用,可以在表头上直观地读出激振力的大小;也可以接示波器观察其波形;还可以接数字电压表精确地读出其力的大小;并能保证在(20Hz～1000Hz)频率范围内输入与输出之间的相位差基本上保持不变,这样就能准确地作出整机或部件的振型图或幅相图。
First, an overview With the widespread domestic dynamic test machine, electromagnetic exciter is more widely used. DJ-type electromagnetic exciter force gauge is based on the electromagnetic exciter, developed according to the requirements of use. It is used in conjunction with the electromagnetic exciter, the head can visually read the size of the exciting force; can also be connected to the oscilloscope to observe the waveform; you can also access the digital voltmeter accurately read the size of its force; (20Hz ~ 1000Hz) frequency range of input and output within the phase difference remains essentially unchanged, so that you can accurately make the machine or part of the vibration pattern or amplitude and phase diagram.
