铰接式拖拉机静态一级稳定性分析

ANALYSIS OF FIRST ORDER STATIC STABILITY FOR ARTICULATED TRACTOR

本文探讨铰接式拖拉机转向位置一级失稳坡度角与停机位置的关系,将横向一级失稳与纵向失稳统一起来研究,推导出失稳坡度角随停机方位变化的统一表达式,找到了最小一级失稳坡度角及其停机方位,并用稳定区域图表示全方位的失稳形式和失稳坡度角,最后用模型实验结果验证了理论分析的正确性。

In this paper, the relationship between the first order unstable slope angle at the steering position and the parking position for the articulated tractor was investigated. Integrating the vertical stability with the horizontal first order stability, obtained the general formula which expresses the relationship between the two kinds of unstable slope angle and parking position. The first order unstable minimum slope angle and the corresponding parking position was given out. A whole position expression for the first order unstable slope angle has been completed in the form of the first order stable zone map. At last, the theoretical analysis has been proved by the model experimental results.
