【摘要】 概述了后座冲击条件下的绝热压缩点火模型和有限压缩速率点火模型,分析了这两种模型存在的不足,提出了热、力学耦合的压缩加热模型。并用考虑应变率影响的热弹塑性模型对B炸药装药在后座冲击下的温升进行了计算。更多还原

【Abstract】 In this paper the adiabatic compression ignition model and the finte compression rate ignition model subjected to setback impact are summarized and the insufficiencies of these two models are analyzed. The coupled compression ignition model of thermotics and mechanics is advanced. And the Comp B explosive charge’s temperature rise subjected to setback impact are caculated by using the thermo elastic plastic model considing the effect of strain rate.更多还原
