| Abstract: | By means of the simulation capability of Matlab and Simulink,the simulation analysis of the movement track and the speed characteristics are done for the ditching tools and the soil,and analyzing visually on the impact factors of the throwing-soil performance of the super-large-disc ditcher at the up-cut and small-space operation.Combining with the stress analysis of the soil unit cut process of this equipment,the methods are given to improve its ability of throwing-soil and lifting-soil,and its working parameters optimization.A new approach is provided for the design of this equipment. |
