The invention provides a flexible water-permeable oscillation suppression device for a C-shaped liquid tank, which can achieve the purpose of reducing the damage of liquid oscillation to a tank body structure, and mainly comprises a rigid base with a groove and a flexible water-permeable oscillation suppression plate capable of being inserted into the groove. The base is symmetrically fixed to the center of the wall of the C-shaped liquid tank in a welded mode, and due to the installation position, the oscillation suppression devices can directly act on high-speed fluid close to the free liquid level, and the two oscillation suppression devices can be arranged in the length direction according to the length of the C-shaped liquid tank. The oscillation suppression plate adopts a flexible structure, so that the oscillation suppression plate can move and deform in a larger range to better absorb an impact load generated by oscillation, and the oscillation suppression plate does not easily generate safety problems such as a fatigue effect; different from a solid plate, the flexible water-permeable swash plate is provided with water-permeable holes, swash devices with different water-permeable rates can be replaced according to different working conditions, fluid generates obvious eddy current when passing through the holes, and energy in the sloshing liquid tank is dissipated.
本发明提供了一种用于C型液舱的柔性透水制荡装置,可以达到降低液体晃荡对舱体结构产生危害的目的,其主要包括带有凹槽的刚性底座和可插入凹槽的柔性透水制荡板。底座通过焊接方式对称固定在C型液舱壁的中心位置,这样的安装位置可以使制荡装置直接作用于近自由液面的高速流体并可根据C型液舱长度沿长度方向布置两道制荡装置;制荡板采用柔性结构可以发生更大范围的运动和变形更好地吸收晃荡产生的冲击载荷,本身更不易产生疲劳效应等安全问题;不同于实体板,柔性透水制荡板上开有透水孔,可根据不同工况更换不同透水率的制荡装置,流体通过孔隙时产生明显的涡流,耗散晃荡液舱内的能量。
