Reconstruction and Deduction Algorithm of the Experimental Load Spectrum Based on Discrete Regularization
Aimed at eigenvalues for pick cutting coal and rock in random process to extract more difficult,to provide theoretical basis for the exploration method of high efficiency cutting broken coal and rock,according to the experimental load spectrum of the limited conical pick and its structure and motion parameters,the paper introduces the determination of the reconstruction algorithm and the characteristics of load spectrum,deducing the load spectrum of pick cutting coal and rock under different parameters,the topological relations and development algorithm is presented for the different wedge angle parameters,to explore the deduction law of the load spectrum.Based on discrete regularization method(DRM),the regularized parameter is selected by combining the Morozov discrepancy principle and Newton iterative scheme,to reconstruct the load spectrum,as well as,the characteristic parameters of the load spectrum is extracted.The results show that reconstruction and deduce the cutting load spectrum can express pick the actual crushing state,the mathematical description of the load spectrum derivation is established under different parameters,the load spectrum of reconstruction ?40and ?45wedge angle,which the mean and amplitude with real-time correlation in the time domain,reconstruction and deduction algorithm provides an effective method for the quantitative inversion of cutting load.
