【Abstract】 The kinematic behavior of working component of a bionic trench digger is complicated when the component is being out of soil. In order to select reasonable design parameters and to obtain good performances for out of soil, the kinematic analysis was carried out. The mathematical expression of the change of working speed of the blade during out of soil was developed. This model could be used as the basis of calculating the max and average powers required during the digger out of soil.更多还原
