摘要:
为了探究爆炸切断TC4钛合金板的最佳方式，设计了轴向单孔和轴向双孔两种装药结构。采用AUTODYN软件进行了数值模拟，并结合试验分别对单孔装药和双孔装药优劣性以及装药孔径对爆炸切断效果的影响进行了对比分析。通过计算装药量及运用Mises屈服准则，判断了两种装药结构下4组试验方案中TC4钛合金板的切断及损伤情况，且结合测点振速与加速度变化情况说明了应力波在板内的传播规律。结果表明：爆炸切断能力会随着装药直径的增大而增强，且钛合金板的损伤也随之增大；相较于单孔装药，双孔装药更适用于爆炸切断TC4钛合金板。
Abstract:
In order to explore the best way of explosive cutting of titanium alloy plate, two charge structures of axial single hole and axial double holes were designed. Numerical simulation was carried out by using AUTODYN software. Combined with the test, advantages and disadvantages of single-hole charge and double-hole charge, and the influence of charge aperture on the explosion cutting effect were compared and analyzed. By calculating the charge amount and using Mises yield criterion, the cutting off and damage of TC4 titanium alloy plate in four test groups under the two charge structures were determined, and the propagation rules of the stress wave in the plate were explained in combination with the variation of vibration velocity and accelerated velocity at the monitoring points. The results show that the explosion cutting capability will increase with the increase of charge aperture, and the damage of titanium alloy plate will also increase. Compared with single-hole charge, double-hole charge is more suitable for explosive cutting of titanium alloy plate.
