摘　　要：文章运用流体力学和热力学原理,建立了列车运行状态下车厢内对流换热的数学模型,并运用模型试验相似理论对该数学模型进行了相似分析,确定了模拟热平衡试验时保持车厢内空气的对流换热与实际运行时相似的准则,并且对试验方法进行了讨论。This article utilizes the hydromechanics and thermodynamics principle,had established the mathematical model of the heat convection in the train movement condition compartment,and had carried on the similar analysis using the model experiment similarity theory to this mathematical model,had determined when simulation thermal equilibrium experiment,maintains in the compartment when the air heat convection and the actual movement similar criterion,and discussed experiment methods.
