Establishment and Analysis of Matlab-Based Operation Model of Hole Digger Blade
Through the establishment of trapezoidal blade motion model,analyse the factors related to the sliding cutting speed of the soil cutting blade of the digging machine,and conclude that there is a tilt angle between the blade edge and the horizontal direction,and the angle between the soil mass and the horizontal direction is significantly related to the sliding cutting speed,and use MATLAB to analyse and combine with the practical operation experience to conclude that the specific value range of the blade edge tilt angle of 20 °～30 ° is preferred;establish a pure cutting model for the blade.Based on the mathematical language,the theoretical analysis of blade installation angle and edge inclination angle is carried out,and the reasonable value range is given through MATLAB programming.
