| 摘 要： | 应用三维建模软件PRO／E建立了某履带车辆散热系统的进排气蜗壳、风扇和散热器等部件的三维模型，并运用FLUENT6．3软件对不同蜗壳结构对冷却系统风量的影响进行了仿真分析，提出了改变风扇安装位置、增加排气蜗壳出口斜面以及取消进排气蜗壳分型面等优化建议．仿真结果表明，在不增加冷却系统体积的前提下，通过优化措施，冷却系统风茸提升了8．3％．

| Abstract: | The CAE model of compartments of cooling system of a tracked vehicle is established by Pro/E.The numerical simulation and the analysis for the influence on air flux of cooling system by different structure of volutes are made by FLUENT6.3.The paper also presents some advice about optimum design,such as optimizing the position of fan,adding an inclined plane of volute outlet and deleting the parting plane of volute.The result shows that the air flux of cooling system has increased 8.3% without augmenting the volume of cooling system. |
