【摘要】：从斜板角度和折角形式两个方面对油船底边舱的上、下折角点进行优化设计。以常规的焊接型折角为研究对象,分析了四组不同斜板角度的有限元模型。根据应力和疲劳寿命曲线,得到了斜板的最优角度。比较了圆弧型折角与焊接型折角的应力水平与疲劳寿命。结果表明:圆弧过渡能降低上、下折角点的应力峰值,焊接型折角的嵌接肘板能提高下折角点的疲劳寿命。在此基础上,研究了圆弧型折角对斜板最优角度的影响。
[Abstract]:This paper optimizes the design of the upper and lower corner of the bottom side of the tanker from the angle of inclined plate and the form of angle. The conventional welding angle is taken as the object of study. The finite element models of four groups of different inclined plate angles are analyzed. According to the stress and fatigue life curves, The optimum angle of inclined plate is obtained. The stress level and fatigue life of arc angle and welding angle are compared. The results show that the arc transition can reduce the peak stress of the upper and lower corner points. The fatigue life of the lower angle can be improved by the welding elbow. The influence of the arc angle on the optimum angle of the inclined plate is studied.
