A high‐pressure shock wave generated by a donor charge subjected to an underwater explosion can sympathetically detonate an acceptor. Experimental research is the most effective method of studying sympathetic detonation because information regarding pressure evolution, pressure peak, and bubble pulsing cycle can be obtained directly. In this study, a set of underwater sympathetic detonation tests were conducted to investigate the pressure characteristics and critical distance for the sympathetic detonation of a 1‐kg TNT donor and acceptor charges. Following the experiment, the energy, pressure, and bubble pulsing cycle were empirically analyzed. The results indicate that the best transmission and safety distances for sympathetic detonation were 99.55 and 128.92 mm, respectively. The acceptor charges were partially detonated by the donor when the gap distances were 109.90 and 119.98 mm. The degree of sympathetic detonation can be determined by analyzing the energy, bubble pulsing cycle, and pressure evolution.

水下交感爆轰研究

供体装药在水下爆炸时产生的高压冲击波会同情地引爆受体。实验研究是研究交感爆轰的最有效方法，因为可以直接获得有关压力演变，压力峰值和气泡脉动周期的信息。在这项研究中，进行了一组水下交感爆轰试验，以研究1 kg TNT供体和受体装药的交感爆轰的压力特性和临界距离。实验之后，根据经验分析了能量，压力和气泡脉冲周期。结果表明，交感爆轰的最佳传输距离和安全距离分别为99.55和128.92 mm。当间隙距离为109.90和119.98 mm时，供体部分引爆了受主装药。可以通过分析能量，气泡脉动周期和压力演变来确定交感爆震的程度。
