| Popis: | When military vehicles are subjected to a mine blast, the vehicles will be damaged and the occupants will be injured. The main objective of this paper is to study the feasibility and accuracy of the drop tower to simulate the response of the vehicle body under the actual explosion condition. The equivalent damage method of impact waveform simulation was studied, and the feasibility of the equivalent damage principle of impact waveform based on change in velocity was verified. By analyzing a large number of data of simplified seat impact simulation, the mechanical model of the drop tower was analyzed. Through the correlation study of the parameters of the drop impact load, the relation formula of the drop height required by the target load was constructed, and the customization of the impact load was realized. The response simulation of the protective seat in the explosion was completed in the drop tower, which verifies the accuracy of the drop tower in simulating the explosion impact load. In addition, the results provide a good basis for the follow-up research. |
