查找炮弹膛炸原因,通常要进行全尺度试验。这些试验试图模拟人们猜测的导致早炸并形成破坏模式的事件先后顺序。它们费时而又昂贵。本文研究了应用小尺度物理模型模拟高能炮弹在4.5英寸炮膛内早炸所产生的破坏模式的可行性。结果表明:虽然小尺度模型用以模拟总体破坏模式的准确性需要进一步研究,但是应用这种模型可以再现破坏的几个重要特征。
Find the cause of bomblet bombing, usually to carry out full-scale test. These experiments attempt to mimic the sequence of events one might guess that led to the early frying and the destruction patterns. They are time consuming and expensive. This paper studies the feasibility of using small-scale physical model to simulate the failure modes of high-energy projectile in 4.5-inch borehole. The results show that although the accuracy of the model for simulating the total failure mode needs to be further studied, the application of this model can reproduce several important features of damage.
