| Abstract: | In this paper, the traditional method to analyze the forces acted on three hitch plough wasqueried, and its errors were pointed out and the reason resulting in the errors was researchedin theory.3-D balance equations of the forces applied to the plough were set up and pro-grammed. On the basis of the result of calculation the influence of different values of the fac-tors on forces and torque acted on the plough was evaluated. |
