摘　　要：本文采用溢流阀的加载方法,对脉冲数字流的流体脉冲性能进行了实验研究。考察了在不同脉冲频率、工作油液流量、油源供油压力及每次产生脉冲个数多少不同等情况下量化单位的变化及其规律,并结合流体系统的要求,分析了不同工况下流体脉冲压力信号波形的特点。In this paper, the fluid pulse behaviors of pulse digital flow were investigated experimentally with relief valve loaded.The variation and its pattern for a quantization unit were considered when the pulse frequencies, the working oil flowrate,the working pressures and the numbers produced pulses each time operation were different. Meantime, the pressure waveform characteristics of fluid pulse signal at various working conditions were analyzed and explained in accordance with the requirements for fluid systems.
