| 摘 要： | 研究了应用测周期法和常规数据采集设备对柴油发动机进行瞬时转速测试．针对采样频率不够高导致瞬时转速测试分辨率过低的问题，提出采用插值的方法，对用较低采样频率采集到的原始信号进行插值处理，以提高采样频率或求得精确过零点，从而显著提高了发动机瞬时转速测试精度．

| Abstract: | Period measurement method and general data collection equipment was employed to measure the rotation speed of diesel in transient operation status. Aimed at the problem of low sample rate leading to low measurement distinguish rate of transient speed, interpolation method was present. Interpolation was used to analyze original data collected by low sample rate to improve sample rate or acquired precise zero points. This method improves the measuring accuracy marked. |
