摘要:
为了了解一种流线型传感器结构对水中爆炸冲击波传播的影响规律，利用有限元方法对这种流线型传感器结构附近的水中爆炸冲击波传播过程进行数值模拟，研究分析了这种流线型传感器结构对水中爆炸冲击波传播的影响规律。研究结果表明，这种流线型传感器的前端锥体结构会使传感器结构表面冲击波增强，冲击波压力增大。传感器结构外径尺寸越大，对冲击波的增强作用越明显，前端锥体结构锥角高度不同的传感器结构对冲击波增强作用没有显著差异。
Abstract:
In order to study the influence of a kind of streamline sensor structure on underwater explosion shock wave, numerical simulation of underwater explosion shock wave transmitting around such sensor structure was performed by finite element method. The results show that the cone structure in front of the sensor can enhance the shock wave that transmits on the surface of sensor structure.Thereby the overpressure of shock wave becomes greater.The larger the outer diameter of the sensor structure, the more evident the effect that the sensor structure enhances the shock wave. Whereas under different cone angles in front of the sensor, the effect of the sensor structure on enhancing the shock wave is not evident.
