摘要
本文研究了用间距为l_2两点瑞利波脉冲响应的互相关或互谱相位求耕作土层应力波速的方法。用此法测定了几种土壤的应力波速,所测结果在土壤高速切削机理研究中得到应用。
This paper studied the method that the stress propagation velocity of tillage soil was obtained by means of the cross-correlation function or cross-spectral function of Raylight wave impulse responses about two point of l2 interval. The stress propagation velocity of various soil was measured by means of the method. Measured result was applied in the study on soil high speed cutting mechanism.
