| 目的 在相同罐体条件下，分别探究不同内容物的罐体静态压缩及动态跌落实验结果的差异性。方法 针对常见的空气、液体、固体内容物的3类罐体进行静态压缩和动态跌落实验，以跌落方式、跌落高度、测试位置为变量对比分析不同罐体的最大加速度拟合曲线。结果 在静压实验中，空气罐应力集中在下方，液体罐和固体罐应力集中在上方。在跌落实验中，3类罐体的最大加速度值均有差异，差值最大为1.59 km/s2；2种跌落方式下，由上至下，空气罐身应力分布呈三次函数，极值点与对称中心受跌落高度影响较大；液体罐身应力分布呈正弦函数，幅值和初相受跌落高度影响较大；固体罐身应力分布在平跌落与45°角跌落下分别呈指数函数和二次函数，受跌落高度影响不大。结论 内容物不同，容器的静态压缩实验结果不同，动态冲击实验结果有显著差异，跌落方式对容器的动态跌落结果有较大影响。 |

| The work aims to explore the otherness in test results of static compression and dynamic drop between the same tanks with different contents. Static compression and dynamic drop tests were carried out on three tanks with normal air, liquid and solid. The maximum acceleration fitting curves of different tanks were compared and analyzed by drop mode, drop height and test position. In static compression, the stress of the air tank was concentrated in the lower part, and the stress of the liquid and solid tanks was concentrated in the upper part. In the dynamic drop, the maximum acceleration of three tanks was different, with a maximum difference of 1.59 km/s2. Under the two drop modes, from top to bottom, the stress distribution of the air tank body presented a cubic function, and the extreme point and the center of symmetry were greatly affected by the drop height. The stress distribution of the liquid tank body was sinusoidal and the amplitude and the initial phase were greatly affected by the height of the drop. Solid tank body exhibited an exponential function during horizontal drop and a quadratic function during the drop with the angle of 45°. The drop height had little effect on the curve. With different contents, static compression test results are different, dynamic impact test results are significantly different, and drop mode has a great impact on the dynamic drop results. |
