摘　　要：发展了一个基于集总参数法的坦克动力装置非稳态传热模型,考虑了发动机燃烧室的传热、发动机主要部件的传热、冷却系统和润滑系统的工作及坦克动力舱内的空气流动,建立了燃烧气体与发动机部件、各部件之间、部件与冷却液、部件与润滑油、部件与动力舱空气之间的热耦合计算公式.对一台坦克动力装置的非稳态传热进行了实例计算,结果证实这个模型可以用于坦克动力装置非稳态传热的研究.Based on the lumped parameter method,an unsteady heat transfer model is developed for a tank power device,in consideration of heat transfer in the engine combustion chamber, heat transfer among major engine components, cooling system, lubricating system, and power cabin airflow. The thermal coupling calculations are formulated including the combustion gas and the engine parts,between the parts,the pans and the coolant liquid,the parts and the lubricant oil,the pans and the air in the power cabin. An example simulation is implemented under the condition of an unsteady heat transfer in its power device of a tank. The results show that this model is suitable for studying unsteady heat transfer of the tank power device.
