Abstract

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.

目前，微耕机已经成为中国西南广大丘陵山区不可缺少的农业机械。为了改善其操作舒适性，做了许多研究，但是效果很小。因此，开发了一种新型电动微耕机，为了进一步改善其操作舒适性，采用仿真分析和田间试验相结合的方法来减小扶手处的垂向力和振动加速度值。结果表明，在正常工作条件下，当重心位置移动19.78 cm时，垂向力由154.24 N减小到0 N，振动加速度值减小20.16％。
