摘　　要：研究某型强光爆震弹的冲击波超压致伤特性。为得到某型强光爆震弹对于人员致伤的安全半径,依据LS-DYNA结构非线性分析工具,结合爆炸冲击波超压的致伤效应理论,建立了相应的仿真模型并进行实验分析。先基于理论公式进行计算,对比理论计算数据和仿真数据,通过数值拟合,得出了仿真结果与理论计算结果的对比曲线,并结合实际分析了仿真数据的可靠性。结果表明,利用仿真数据可以计算出冲击波超压对人员致伤的安全半径,并具有一定的实践指导意义。The study is about a certain type of light knock＇ s shock wave overpressure in injury characteristics. In order to get a certain type of light knock＇ s the safety radius in personnel injury, based this on I..S-DYNA nonlinear a- nalysis tools and combined with the explosion shock wave overpressure＇ s injury effect theory, we established the cor- responding simulation model and carried out the experimental analysis. First of all, based the calculation on the theo- retical formula and compared the theoretical calculation data with the simulate data, using the numerical fitting, we obtained the curve lines from the simulation result, and compared it with the results of theoretical calculation. Then we analyzed the reliability of the simulation data combining with the actual. The results show that the simulation data can be used to calculate the shock wave overpressure＇ s safety radius in personnel injury radius which has certain guiding significance in practice.
