Calculation Analysis of Thermal Stress of Propellant Grain in Ignition Process
摘要
Abstract
Based on the heat conduction mechanism of propellant grain in ignition process, the Fourier heat conduction law and non-Fourier heat conduction law are adopted to build the models describing the ignition process. The distribution of the thermal stress about propellant grain is achieved by the calculation formula of thermal stress. The mechanical property of the propellant grain and its fracture way is systematically analyzed by numerical calculation, and the microcosmic failure behaviors of the propellant grain under the conditions of thermal stress and combustion gas wave action in the ignition process are studied by the failure function. The reason of the breech blows is explored.关键词
