本文研究转向工况的静态一级稳定性,将横向一级失稳与纵向失稳统一起来研究,通过分析各失稳形式的失稳特征,得到静态一级失稳坡度角随停机方位的变化关系及各失稳形式的失稳坡度角统一表达式,找到了最小静态一级失稳坡度角及其所在的停机方位,并用静态一级稳定区域图来表现全方位的失稳形式及失稳坡度角大小,最后用模型实验的结果验证了理论分析的正确性。
In this paper, the static first-order stability of steering conditions is studied, and the unilateral instability and longitudinal instability are studied. By analyzing the instability characteristics of each instability form, the variation of the static first-order slope angle with the stopping position is obtained Relationship and the instability slope angle of each instability form unified expression, found the minimum static first grade slope angle of instability and the location of the downtime, and the use of static first-order stable region diagram to show the full range of instability and instability Slope angle size, the final model test results verify the correctness of theoretical analysis.
