摘要

摘要: 以某履带车辆前置动力舱为研究对象，建立了舱内冷却空气流场的物理模型与数学模型，对装备有多个散热器且入口边界条件不同的动力舱内、外部冷却空气流场进行了仿真研究，并与实车测试结果进行了对比，分析了不同车速对各散热器冷却空气质量流量的变化规律的影响.结果表明：在相同风扇转速下，随着车速由0km/h增加到70km/h，两个散热器及两个风扇的质量流量均有10%左右的变化，但是两个散热器的总质量流量基本不变.车速在0~70km/h变化时，由仿真计算和试验测试所得的各散热器和风扇的冷却空气质量流量变化率之差都小于5%.

Abstract: Cooling air flow fields of front power compartment in tracked vehicle were researched,while both physical and mathematical models were built.Cooling air flow fields around inner and exterior of a power compartment equipping with several radiators with different entry boundary conditions were simulated.These studies were compared with the experimental results.The influence of vehicle speeds on change regular of cooling air mass flow of radiators was analyzed.The research shows that,under the same rotating speed of the fan,mass flows of two fans and two radiators change about 10% from 0 to 70km/h of vehicle speeds,and the total mass flow of two radiators is nearly stable.For the radiators and fans,the change rate of cooling air mass flow between the simulation and experiments are less than 5% when vehicle speeds change from 0 to 70km/h.
