摘　　要：研究了不同充液比下,防波板上孔洞的设计对液罐车纵向稳定性的影响。研究表明,在充液比为0.8、罐内装有两块防波板的条件下,对抑波效果影响最大的因素是防波板顶部气孔形状,其次是中部阻尼孔形状,最后是底部通液孔形状;抑波效果最佳的防波板上孔洞形状的组合是:顶部气孔为半椭圆孔、中部阻尼孔为圆形孔、底部通液孔为半圆形孔,此时罐车前封面受到的最大液体冲击力较低,且后续液体冲击力波动较为平缓。The influence of the design of the holes on the breakwater plate on the longitudinal stability of the tanker under different liquid filling ratios is studied in this paper.The results of optimization design show that under the condition that the liquid filling ratio is O.8 and two wave shields are installed in the tank,the most important factor affecting the wave suppression effect is the shape of the air hole at the top of the wave shield,followed by the shape of the damping hole in the middle,and finally the shape of the liquid vent hole at the bottom;The combination of hole shapes on the wave plate with the best wave suppression effect is:the top hole is a semi elliptical hole,the middle damping hole is a circular hole,and the bottom liquid vent hole is a semi-circular hole.At this time,the maximum liquid impact force on the front cover of the tank truck is low,and the subsequent liquid impact force fluctuates gently.
