A cylindrical tank model with lid was made from vinyl chloride film of which thickness was 0.5mm. The tank model has 84mm in diameter and 200mm in height. Setting the tank with some water on a shaking table,we carried out experimental vibration test under periodic harmonic external forces. Under various shaking table acceleration and frequency of the external force, 4 points of the tank displacement and 16 points of strain in circumferential direction of the cylindrical tank were measured. Then we analyzed the response of the tank and showed displacement response curves corresponding to harmonic oscillation, the 2nd and the 3rd higher-harmonic oscillations, and 1/3-subharmonic, 1/2-subharmonic and 3/2-subharmonic oscillations. Each vibration mode response curve in circumferential direction of the tank corresponding to those harmonic, higher-harmonic and sub-harmonic oscillations was also showed.Natural frequencies and displacement response curves obtained from the test were compared with the results obtained by applying a linear analysis of an interactive behavior of tank and potential fluid.

用0.5mm厚的氯乙烯薄膜制作了带盖圆筒形罐体模型。坦克模型直径为84毫米，高度为200毫米。将装有水的水池置于振动台上，进行了周期简谐外力作用下的振动试验。在不同的振动台加速度和外力频率下，测量了圆筒形储罐在周向的4个位移点和16个应变点。然后分析了贮箱的响应，给出了简谐振动、二阶和三阶高次谐波振动、1/3次谐波振动、1/2次谐波振动和3/2次谐波振动对应的位移响应曲线。给出了简谐、高谐和亚谐振动时贮箱周向各振型的响应曲线，并将试验所得的固有频率和位移响应曲线与贮箱与势流相互作用的线性分析结果进行了比较。
