摘　　要：介绍了DK-Ⅲ型轴系扭振测量仪的总体设计与各部分功能实现。该型测量仪基于脉冲时序计数原理设计,在前端信号处理部分引入跟踪滤波和峰值时序检测技术,并利用大规模可编程逻辑器件和USB接口完成系统逻辑设计及数据通信。在挠性转子实验台上的扭振测量实验表明,DK-Ⅲ型扭振测量仪可实现轴系扭振的较高精度测量。The overall design and functional implementation of DK-Ⅲ shafting torsional vibration are introduced. The instrument has been designed based on pulse sequential counting principle; trace filtering and peak sequence detection are involved in frond-end signal processing sec- tion; by adopting large scaled programmable logical device and USB interface, the logic design and data communication are achieved. The ex- periment carried out on flexible rotor test bench for torsional vibration measurement shows that the DK-Ⅲ instrument is able to accomplish high precise measurement.
