Experiment method proposal on sloshing behavior of real scale floating-roof-tank

储油罐液体晃动现象是由2003年东京大地震引起的。这一现象对Tomakomai的储油罐造成了严重的破坏，引发了火灾，并导致浮顶下沉。在这起事故发生后，已经开始对液体晃动引起的浮顶的各种动态行为进行验证，并希望在真实的尺度水平上与水箱进行验证。在此基础上，提出了浮顶油罐产生晃动现象的实验方法。该方法利用装有气缸的波浪发生器激发液体晃动现象的装置，使储罐中的液体运动起来。结果，我们成功地在实际水箱中产生了液体晃动，并得到了合适的液体晃动的阻尼系数。

The liquid sloshing phenomenon of oil storage tank was excited by the 2003 Tokachi-oki Earthquake. This phenomenon caused severe damage to oil storage tanks at Tomakomai igniting fire and sinking floating roofs. After this accident, verification of various, dynamic behavior of a floating roof due to liquid sloshing have been begun and it has been desired to verify it with the tank at the real scale level. Then, we propose the experiment method of generating the sloshing phenomenon in the floating roof tank using a real tank. This method uses the excitation equipment of the liquid sloshing phenomenon by the Wave Generator with air cylinders which is set up and moves the fluid in the tank. As a result, we succeeded in the generation of the liquid sloshing in a real tank and obtained appropriate damping factor of the liquid sloshing.
