This paper describes the experimental setup of combustion chamber, and the shock loads resultant of gases mixture detonation. The results of experiments performed with fully clamped circular steel plates subjected to detonation of acetylene (C2H2)–oxygen (O2) in various volume ratio and different initial pressure. The energy of deformation of plates is determined by measuring pressure of explosion chamber after detonation and the results presented in terms of central deflection of the plates. Also, in this paper, theoretical modelling is presented to predict the midpoint deflection versus impulsive loading by assuming a zero Bessel function shape of the deformed circular plate. This approach is developed based on energy method for plastic material behaviour, and since the shock wave energy is equal to the deformation energy. The strain energy of the plate can be calculated by using the initial shock load energy imparted to the circular plate. The results of this model have good agreement with the experimental values. Moreover, it has been shown that the obtained model has much less error compared with those previously proposed in the literature.

混合气体爆轰成形圆夹板实验研究与分析建模

本文描述了燃烧室的实验装置，以及气体混合物爆轰产生的冲击载荷。用完全夹紧的圆形钢板在不同体积比和不同初始压力下进行乙炔 (C2H2)-氧气 (O2) 爆炸的实验结果。板的变形能量是通过测量爆炸后爆炸室的压力来确定的，结果以板的中心挠度表示。此外，在本文中，通过假设变形圆板的贝塞尔函数形状为零，提出了理论模型来预测中点挠度与脉冲载荷的关系。这种方法是基于塑性材料行为的能量方法开发的，因为冲击波能量等于变形能量。板的应变能可以通过使用赋予圆形板的初始冲击载荷能量来计算。该模型的结果与实验值具有很好的一致性。此外，已经表明，与先前在文献中提出的模型相比，所获得的模型误差要小得多。
