摘要
针对在密闭空间中爆炸产生的冲击波导致混叠冲击波对内壁毁伤较为复杂的问题,提出一种分离混叠冲击波的解算方法。通过正演模拟分析密闭空间内混叠冲击波对内壁面的毁伤,得到壁面上的冲击波是多次混叠的。建立独立冲击波的全波形模型,并采用量子粒子群优化(QPSO)算法,对多次混叠冲击波进行分解和拟合。QPSO算法拟合出独立的冲击波,其仿真结果相较于遗传算法,均方根误差从0.2506降至0.1216,平均相对误差从0.1079%降至0.1059%。
To address the complex problem of overlapping shock waves causing damage to the inner walls in an enclosed space due to an explosion,a method for separating overlapping shock waves is pro⁃posed.By using forward modeling to analyze the damage caused by overlapping shock waves to the inner walls of an enclosed space,it was determined that the shock waves on the wall are overlapped multiple times.A full waveform model of the individual shock waves is established.The Quantum Particle Swarm Optimization(QPSO)algorithm is then employed to decompose and fit the multiple overlapping shock waves.The QPSO algorithm fits the individual shock waves,and the simulation results show that compared to the Genetic Algorithm,the root mean square error decreased from 0.2506 to 0.1216,and the mean relative error decreased from 0.1079%to 0.1059%.
