介绍某压气机实验台建设中的测控方案。对于数据采集过程中的各种压力信号
提出了适用于叶轮机械稳态特性采集的经济性方案。针对各种动态干扰噪音
详细分析了噪声源的产生及其干扰方式
发展了利用采集技术判断干扰源的方法
并采取了具有针对性的抗干扰措施。为后续实验的进一步展开奠定了基础。
A system for measuring and control of some compressor experiments in a test cell is described.An economical scheme
which is effective for the steady data acquisition for turbomachinery
has been demonstrated forward.By dint of the analysis of sources and influencing modes from the dynamic interferential signals
a method that can estimate the jam source is developed
and accordingly the remedies are taken.All this work provides the basis for the further experiments.
