| Abstract: | In this paper, the measuring methods using magnetoelectric transducer were illuminated, and the measure errors of transient speed were analyzed systemically which comprised the counting error and the error by shaft center track. For eliminating the counting error, the interpolation method was applied to improve measuring precision. The axis orbit had the direct influence on the transient speed measurement, it might modulate the output signal of transducer in frequency and amplitude. Through deeply analyzing the mobile rule, the corresponding solving method was proposed. At last the simulation calculation proved that the axis orbit disturbed measuring transient speeds, and the proposed solving method was effective. |
