水平激励下椭圆环形截面储液罐内液体的晃动响应
DOI: 10.3969/j.issn.1671-7627.2014.04.016, PP. 84-88
Keywords: 液体晃动响应,解析解,速度势,广义坐标,椭圆环形截面
Abstract:
将受迫晃动的液体速度势分解为刚体速度势和摄动速度势,分别得到满足椭圆环形边界条件的刚体速度势及以自由晃动模态为广义坐标系的摄动速度势。将两者代入液体自由表面波条件,通过自由晃动模态的正交完备性建立动力响应方程,求解得到液体晃动响应的解析解。计算结果与有限元结果非常吻合。分析结果表明:储液罐内液体超过一定高度后,液面晃动波高响应将不受液体高度变化的影响;液面晃动波高响应具有滞后性。
