| Abstract: | The multi-body dynamic model of the tracked of orchard vehicle was created using the software RecurDyn/Track(LM), and focus on the two kinds of working condition on straight system and steering system of the tracked of orchard vehicle doing dynamic performance simulation and estimating stable performance of the machine. The results show that the whole machine model is effective through the analysis of the ground pressure, the depth of the subsidence, walking resistance, steering angular velocity and steering angle acceleration of the caterpillar vehicle. It was tested about and 180°of flat ground steering,test showed that the model of machine is effective.It validates the correctness of the model and provides a theoretical reference for the further improvement of the hill-side crawler tractors. |
