Xiaodong Zhang · Machinery Design and Manufacture · 2009
Signals of dynamic measurement error include multi-component and non-stationary signals,the analysis and treatment of dynamic measurement error should combine many methods of signal process,because of complex component of signals. For example,Fourier transform,Wavelet transform, methods of signal process,and its application in non-stationary signals,establish system of analysis and emulation of dynamic measurement error,analyze the output of dynamic measurement error of the system, and analytical combined error,find combined error causing by all units of simplex error,supply academic laws for dynamic accuracy assessment,diagnose and control dynamic error in more accurate way.
