利用走时层析方法重建水中爆炸冲击波超压场,用于进行水中爆炸威力测评。针对该方案对重建区域分辨率的要求,提出了对待重建区域采用疏密相间网格和自适应网格结合的变网格技术,旨在用较少数目的传感器重建出较高分辨率的超压场。建立了水中爆炸场重建模型,利用Matlab进行仿真试验。仿真结果表明,相比传统的规则网格重建方法,该方案重建精度更高、收敛速度更快。
Using time-of-flight tomography to reconstruct the overpressure field of blast shock wave in water, it is used to evaluate the power of underwater explosion. In view of the requirement of reconstructing the regional resolution, this paper proposes a modified meshing technique using dense and dense meshes and adaptive meshing in the region to be reconstructed, aiming to reconstruct a higher resolution super-resolution with a smaller number of sensors Pressure field. The establishment of a waterburst reconstruction model, the use of Matlab simulation test. The simulation results show that the proposed method has higher reconstruction accuracy and faster convergence than the traditional method of regular mesh reconstruction.
