Shearer Shaft Roundness Error of Signal Processing


Article Preview

For the measurement of shearer shaft geometry signal contain the axis of rotation error and the measurement error, made of two separate programs from shearer shaft the geometric method of measuring signal acquisition and signal processing error. The program is based on the analysis of the shearer shaft Two-point method of roundness measurement method and error separation technique. Using two displacement sensors and a combination of programs to measure the angle sensor, and an equation using the Fourier transform of elimination and separated from the measurement signal roundness. Then, 53H, and wavelet signal Noise algorithm such as the error of roundness error signal separation. Simulation results show that the method has a higher real value and better convergence for coal mining shaft roundness error in the separation of signal processing.
