摘要

Abstract >The property of detonation wave propagation in micro‐channel charges is one of the most important research areas in the field of explosives. Based on DSD (Detonation Shock Dynamics) theory and a linear assumption for the streamline deflection angle, this paper proposes a theoretical model for curved detonation wave propagation in cylinder‐type micro‐channel charges within a strong confinement of metal tube. Further, dynamic control equations related to the detonation velocity and charge diameter are deduced, a numerical calculation method of detonation velocity and shock front shape is given, and propagation rules for detonation waves with different diameters are obtained. An experiment was designed to test the detonation velocities for micro‐channel charges with a booster explosive. The results closely agree with calculations, validating the propagation model of curved detonation waves. It was found that the detonation velocity loss and shock front curvature in the central axis decreased with increasing diameter in the calculation range. Moreover, the smaller the diameter, the greater the rate of change. It is also shown that the model is suitable for the prediction of diameter effects in micro‐channel charges, which is of significance for structural design and performance optimization in MEMS initiation systems. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi

>微通道费用中的爆炸波传播是炸药领域中最重要的研究领域之一。基于DSD（爆震冲击动力学）理论和用于流线偏转角的线性假设，本文提出了一种用于金属管的强大限制内的圆柱型微通道电荷中弯曲爆震波传播的理论模型。此外，推导出与爆轰速度和电荷直径相关的动态控制方程，给出了爆炸速度和冲击前形状的数值计算方法，获得了用于具有不同直径的爆炸波的传播规则。设计实验，以测试带有助力炸药的微通道电荷的爆炸速度。结果与计算密切合法，验证弯曲爆轰波的传播模型。发现中央轴中的爆炸速度损失和冲击前曲率随着计算范围的越来越长而降低。而且，直径越小，变化率越大。还示出了该模型适用于微通道电荷中的直径效应的预测，这对于MEMS启动系统中的结构设计和性能优化具有重要意义。</
