Separation and Solution Method for Superimposed Shock Waves in Enclosed Spaces Based on QPSO
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 0.250 6 to 0.121 6,and the mean relative error decreased from 0.107 9%to 0.105 9%.
