IMPROVING THE OPERATING COMFORT OF THE ELECTRIC MINI-TILLER BASED ON SIMULATION ANALYSIS AND FIELD TEST

Now the engine mini-tiller has become indispensable agricultural machinery in vast hilly and mountainous areas of Southwest China. Many researches have been made to improve its operating comfort, but little effects have been obtained. As an alternative, a new type of electric mini-tiller was developed. For further improvement of its operating comfort, simulation analysis and field test were integrated to decrease the vertical force and vibration RMS values at the handle. The results showed that when the position of centre of gravity moved 19.78 cm, the vertical force was reduced from 154.24 N to 0 N, and vibration RMS values decreased by 20.16% under working condition.
