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.
