Abstract：According to actual physical process of explosive bolt action, it can be divided in time sequence into two stages of explosive unlock and shock. Here, the numerical models for an explosive bolt’s explosive unlock process and shock one under pre-tightened state were established, respectively to analyze effects of main factors of impact load, such as, explosive quantity, pre-tightened force and impact position’s material on structural response under coupled effect. The results showed that in explosive unlock stage, structural responses increase non-linearly with increase in explosive quantity, and increase linearly with increase in pre-tightened force; in near-field, change of explosive quantity dominates structural responses; in mid-field, structural responses are controlled by both explosive quantity and pre-tightened force; in far-field, structural responses are dominated by change of pre-tightened force; in shock stage, structural responses are closely related to material properties of impact position, materials with smaller yield strength and larger plastic deformation ability have better energy-absorbing effect to cause the minimum structural response.
