摘要

为研究破片撞击充液容器引起的液体喷溅特性，开展了液压水锤及液体瞬态喷溅试验，并利用有限元软件ANSYS/LS-DYNA 对该过程进行数值模拟。验证仿真模型的正确性后，研究了液体喷溅特性及破片撞击速度对其的影响。结果表明：主喷溅阶段空泡溃灭所产生的压力远大于低频脉动阶段，而在低频脉动阶段，空泡会反复膨胀与收缩，故低频脉动阶段的压力脉冲持续时间长于主喷溅阶段；空泡溃灭是液体射流产生的直接原因。喷溅流量与侵彻孔处液体压力、侵彻孔附近的液体质量有关；液体射流初始喷溅速度不仅与侵彻孔处液体压力有关，还与侵彻孔附近液体的运动速度有关。

Abstract

In order to investigate the characteristics of liquid spurt caused by fragment impacting the liquid-filled container, hydrodynamic ram and liquid transient spurt tests were carried out, and the process was numerically simulated by ANSYS/LS-DYNA. The rationality of the simulation model is verified, and the influence of the liquid spurt characteristics and the impact velocity of the fragments on it is analyzed. The results show that the pressure generated by the collapse of the cavitation in the main spurt is much greater than that in the low-frequency phase, and in the low-frequency phase, the cavity will expand and contract repeatedly, so the pressure pulse duration in the low-frequency phase, is longer than that in the main spurt; The collapse of the cavity is the direct cause of the liquid jet. The spurt flow is related to the liquid pressure at the penetration orifice, the shape of the penetration orifice, and the quality of the liquid near the penetration orifice. The initial spurt velocity of the liquid jet is not only related to the liquid pressure at the penetration orifice, but also to the velocity of the liquid near the penetration orifice.
