| Abstract: | Taking certain typed ejection seat as the target of study,this paper established a finite element model to carrying out impact dynamics simulation.The response law of seat structure under the effect of impacting loads was analyzed and the weak link that leads to the possible failure in seat ejection was pointed out.The general rule of structural impacts was summarized during the process of simulation,and the influence of response result affected by damping in the course of similar impact was analyzed.Therefore this study provided referencing basis for later study on impact dynamics of complex structure. |
