摘　　要：振动筛实现由不同步到自同步的物理过程中,相位差角是衡量自同步能力的重要参量。为了定量描述相位角的时间历程变化,针对于相位角测试系统的设计是非常有必要的。基于振动筛样机模型为实验研究对象,采用PCI-1780数据采集卡作为测试系统信号采集硬件,同时在Visual Basic设计环境下结合Active DAQ显示控件联合开发测试系统。实验结果表明所得数据与理论值基本吻合。对此,振动筛相位角测试系统可以为同步性理论研究提供实验依据。The physical process of vibrating screen from asynchronous condition to self-synchronous condition is realized. Phasic difference of angle is a important parameter for measuring ability of self-synchronous. In order to quantitatively de- scribe the time course of phase angle change, design based on the test system of phase angle is very necessary. Take the vibra- tion sieve prototype model as the experimental study, it uses the PCI-1780 data acquisition card as a test system signal acqui- sition hardware, combining with Active DAQ controls joint development test system in the Visual Basic design environment. The experimental results demonstrate that the results obtained are in good agreement with the theoretical value. So phase angle of vibrating screen test system can provide the evidence for the synchronism theoretical research.
