| Abstract: | Based on the pervious corresponding investigations,reliability analysis of test method and assessment for blast power of exploder were investigated.Using ANSYS/LS-DYNA program as the computational tool,the propagation rules of shock wave above the ground without obstacles induced by detonator has been studied.The numerical simulation result is compared with the results by the empirical formula calculating results,and the research results suggest that the overpressure is basically coincides with them. |
