摘　　要：为研究密闭爆发器对点火器输出峰值压力和达到峰值压力时间的影响,针对特定点火器,设计了4种长径比、 2种测点的密闭爆发器,在相同激励条件和测试条件下开展相关研究。结果表明:密闭爆发器长径比和测点的位置对结果具有一定影响。在工程应用上优先推荐长径比1.0:1.0、测点位置在长度方向中点处的密闭爆发器。In order to study the influence of closed bomb on the output peak pressure and the time to reach the peak pressure of the igniter, for a specific igniter, a closed bomb with four length-diameter ratios and two measuring points was designed, and relevant research was carried out under the same excitation conditions and test conditions. The results show that the length-diameter ratio of the closed bomb and the measuring points have certain influence on the results. In engineering application, the closed bomb with the length-diameter ratio of 1.0:1.0 and the measuring point in the middle of the length direction is preferred.
