Measurement of Stress Propagation Velocity of Tillage Soil and Its Application to Soil High Speed Cutting

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.
