| Abstract: | The models for the bending in the hole diggers rear-mounted on tractors were analyzed to find out the models that needed to be improved; through examining the energy distribution of the vibration system, the weak points and squandering points were confirmed and positioned, and thus the hole digger design was improved with its vibration-control efficacy tested and verified by electromotive experiments. |
