摘要
分析了有限水域中气泡的运动状态与无限水域中的差异及刚性池壁对气泡脉动的影响。通过水中爆炸试验,测得了距刚性池壁不同距离处Pentolite的气泡脉动周期。在有试验支架和无试验支架两种条件下,测量了Pentolite和两种RDX基含铝炸药的气泡脉动周期。结果表明,随爆心距刚性池壁距离的减小,气泡周期逐渐变大;试验支架的影响也会使气泡周期变大。
The difference of motion state of bubble between free water area and confined water area as well as the influence of rigid wall to air bubble pulsation were analyzed. By underwater explosion test, the period of bubble pulsation of Pentolite in different distance from the rigid wall was obtained. The period of bubble pulsation of Pentolite and two kinds of RDX-based aluminized explosives were tested under the conditions of with and without steel holder. The result shows that bubble period become longer gradually with decreasing the distance between charge and wall. The steel holder makes bubble period become longer.
