测速装置在动平衡仪中占有非常重要的地位.对测速装置的要求是精度高、稳定可靠和检测时间短.针对基于DSP(d igital signal processing)平台的高速转子动平衡测试系统的开发,介绍了一种基于DSP平台的转速基准信号测试方法.文中从转子基准信号的提取、DSP转速测试和软件设计等方面讲述了该方法的实现.这种新的基于DSP的高速转子动平衡转速测试方法精度高、测速范围广、简单方便,适合于对不平衡量所引起的振动量幅值和相位的精确提取.
The device of testing rotational speed is very important to dynamic-balancing testing system. Requirements for the device of testing rotational speed include ： high-accuracy, stabilization, credibility, and shorter testing time. To the development of high-speed rotor dynamic-balancing testing system based on DSP（ digital signal processing）, the way of picking-up rotator reference signal, testing rotator speed based on DSP and the design of software are introduced. This new way of testing rotational speed in high-speed rotor dynamic-balancing testing system based on DSP is accurate, simple, convenient, the range of rotational speed which can test is broad, and the new way is very suitable to pick-up the amplitude and phase of vibration caused by unbalanced amount.
