Research on Different Frequency Display of Pseudo Color in Vibration Velocity Field Measurement
【摘要】 针对振动场速度信号的测试 ,利用数字图像处理与伪彩色信号处理技术 ,以信号总功率为特征值 ,用云图的形式实时地分频显示零部件的瞬态振动速度信号
【Abstract】 Aimed at the testing of velocity signal in vibration field,the velocity signal for twinkling vibration of parts is displayed in different frequency of real-time with a type of nephogram that uses the digital image processing and frequency technology and takes whole power of signal as eigenvalue.
