随着振动技术的发展,目前在各种力学测量中对于磁带记录信息的要求愈来愈迫切,用磁带机取代笔式记录和光线振子示波器的记录方式,使记录信号经回放直接送入计算机或分析仪器,进行分析具有不可比拟的优越性。由于进口磁带机价格昂贵,而使磁带记录不能普遍推广使用。为满足一般工程振动测量的需要,同济大学、兵器部五院与宝应振动仪器厂共同研制了DCJ-1型四通道低频磁带计测仪,线
With the development of vibration technology, the requirements for tape recording information in various mechanics measurements are becoming more and more urgent at present. Instead of using the tape recorder to record the record of the pen record and the optical oscillator oscilloscope, the recorded signal is sent back to the computer through playback or Analytical instruments, analysis has incomparable superiority. Due to the high cost of imported tape drives, tape recording can not be widely used. In order to meet the needs of general engineering vibration measurement, Tongji University, the Fifth Department of Ordnance Department and Baoying Vibration Instrument Factory co-developed DCJ-1 four-channel low-frequency tape measuring instrument, line
