Although much medical research has been done in this field, there has been little research from an engineering approach, and there are many unresolved areas. Since the use of explosives and biological tissues has a lot of safety and ethical restrictions, we propose the observation of a simulated blast using compressed air. In this study, we will construct an experimental apparatus from a design based on numerical calculations and observe the shock wave surface obtained from the instantaneous rupture of a high-pressure chamber in a depressurized environment. The moment of diaphragm rupture is also visualized, and the difference between the two kinds of diaphragm rupture methods is discussed based on pressure waveform.英語フィールド
