The loading process was analyzed to improve performance of delay electric detonator withstanding a high acceleration impact. The consolidating and buffering structures, and delaying technology withstanding impact were also studied. The design of stress distribution, firing, auxiliary ignition, consolidating design of delay element,annular gas storage space structure design were adopted. Thereby, high impact loading test was carried out. Results show that the value withstanding acceleration of the above design structures is higher than 1×105 g and the delay performance is also improved.
