In order to explore the applicability of particle blast method(PBM) in near-field blast problems,PBM and arbitrary Lagrange Eulerian algorithm(ALE & S-ALE) were used to simulate near-field blast tests of AL-6XN stainless steel plates.PBM was used to simulate the near-field blast of a steel plate with different distances to the explosion center.During this process,how the total number of particles and the particle number ratio influence the calculation accuracy of PBM was analyzed.Combined with the test results of T.B rvik,the calculation accuracy and operation efficiency of PBM,ALE and S-ALE methods were compared.By simulating the near-field blast of spherical C4 explosive 150 mm away from the explosion center the steel plate,the time proportion of different algorithms was also analyzed.The results show that under different conditions,the maximum error of steel plate deflection obtained by PBM is 20%,and the dispersion coefficient is 0.12,which is better than ALE and S-ALE algorithm.For the same mesh generation,the operation time of PBM algorithm is only one tenth of that of ALE or S-ALE algorithm.PBM has a higher accuracy and better simulation effect when the particle number ratio is closer to the particle mass ratio under certain total number of particles,or when the total number of particles is higher under certain particle number ratio.
