摘　　要：发展了一个基于集总参数法的坦克发动机热性能模型,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.对一台坦克涡轮增压柴油机的热性能进行了实例计算,结果证实这个模型可以用于坦克发动机热性能的研究.A model based on the lumped parameter method is developed for thermal performance of tank engines. Engine combustion chamber heat transfer, major engine component heat transfer, cooling system, lubricating system, power cabin airflow are included. The heat coupling between the combustion gas and engine parts, one part and other parts, parts and coolant, parts and lubricant, parts and power cabin air are formulated. An example simulation is implemented for a tank turbocharged diesel engine. The results show that this model can be used for studying heat performance of tank engines.
