| 摘 要： | 在压气机流场的动态测试中,为了应用现有的高频压力探针测得更高频率的信号,需要展宽高频压力探针的工作频带。在对高频压力探针进行动态校准的基础上,利用动态补偿数字滤波器技术展宽高频压力探针的工作频带从而改善高频压力探针的动态特性,提高了高频压力探针的响应速度。

| Abstract: | It is necessary to broaden the working frequency band of the existing high response pressure probe to make it can be used to measure the compressor dynamic flow field.On the basis of dynamic calibration,the application of the dynamic compensation digital filter technique will improve the dynamic characteristics,and thus its response time is shortened and the frequency band is broadened. |
