摘要/Abstract

摘要： 热负荷是军用车辆的重要问题，尤其是电传动履带车辆。电传动履带车辆冷却系统设计了3个封闭式循环的水路。根据循环水路中部件的共同点，建立了冷却系统部件动态传热的热容热阻模型，再利用该热容热阻模型，将3个循环水路进行简化，构建了冷却系统动态传热的状态空间模型。对实际冷却系统的动态传热进行循环水降温试验研究表明，该模型可以全面，直观地分析电传动履带车辆冷却系统部件热耦合关系，以及研究稳态工况下热平衡时的冷却系统部件的传热规律，还可以用于冷却系统的故障诊断研究和改良设计。

Abstract: Heat transfer is very important for military vehicle, and especially for an electric drive tracked vehicle. Three closed recycling waterways were designed for the cooling system of an electric-drive tracked vehicle. Based on common points of components in waterways, a heat capacity and thermal resistance model was built for dynamic heat transfer in these components. According to the heat capacity and thermal resistance model, three waterways were simplified, so that a state space model was built for dynamic heat transfer in the cooling system. Experimental study was analyzed for dynamic heat transfer in an actual cooling system. The conclusion is that heat coupling relationship among cooling system components in the electric drive tracked vehicle can be analyzed roundly and visually by that state space model, and that the state space model can be used to find the heat transfer principle of cooling system components, as well as to diagnose fault and improve the design of cooling system.

Key words: heat transfer theory, electric drive tracked vehicle, cooling system, dynamic heat transfer, state space
