摘要: 在孔穴塌缩模型的基础上,建立了计算泡沫态硅橡胶在不同初始密度下的冲击绝热线参数的理论方法。获得了泡沫态硅橡胶在两种不同初始密度下(0.52 g/cm3和0.92 g/cm3)的冲击绝热线,并与已有的实验数据进行对比分析。结果表明,建立的理论方法对于泡沫态硅橡胶的冲击绝热线计算是适用的。Abstract: Based on the pore collapse energy model, a new thermodynamic equation of state was derived to predict and describe the Hugoniot behavior of the silicon rubbers foam with different initial states. The model was tested on the silicon rubbers foam with initial densities of 0.52 g/cm3 and 0.92 g/cm3, respectively. Compared with the corresponding experimental data published previously, the results showed that this Hugoniot model can satisfactorily predict the Hugoniot behavior of silicon rubber foam.
