| Abstract: | To accurately estimate the impact load in the experiment of large aircraft model hitting the concrete target, the test system of the small size of the cylindrical structures hitting the moving target was established. The decreasing acceleration curve of cylindrical structures was measured. Combined with linear density distribution, the impact load curve can be calculated. Compared with the experimental impact load curve, the results of theoretical calculation was verified and the theoretical calculation formula was improved. |
