汽车乘员舱多节点传热模型仿真方法的研究及应用
Research and Application of the Simulation Method for the Multi-node Heat Transfer Model of Vehicle Cabin
基于耦合的一维模型和三维模型建立了汽车乘员舱多节点传热模型的仿真方法,开展了乘员舱部件材料的热物性参数测试和整车环境仓热舒适性测试,并对该仿真方法的计算精度进行了分析。仿真与试验测试结果表明:相比单节点传热模型仿真,多节点传热模型仿真的乘员头部温度预测精度更高,误差在5%以内,可满足工程应用。对某MPV车型的空调出风口设计方案的评估表明,该仿真方法可有效指导汽车乘员舱热舒适性能开发与方案设计。
Based on coupled 1D and 3D simulations, a multi-node heat transfer model for the vehicle cabin was established. Thermophysical properties of cabin materials were measured, and thermal comfort tests were conducted in an environmental chamber. The simulation accuracy was then validated. The results show that the multi-node model predicts occupant head temperature with higher accuracy (error within 5%) than the traditional single-node model, and meets engineering requirements. Evaluation of air conditioning outlet designs for an MPV model indicates that the proposed method can effectively guide the development and optimization of cabin thermal comfort performance.
