摘　　要：传统的舱室热环境CFD仿真计算方法通常仅考虑舱内流体域的气流组织,忽略了固体域的影响。利用恒定送风边界条件,忽略了空调系统本身的动态响应,这导致了无法准确模拟舱室热环境的动态变化。故针对某型特种车辆,建立了舱室及乘载员三维物理模型。通过流固耦合及边界条件修正法,分别对舱室壁面及舱内固体区域进行了处理,考虑固体域对舱室热环境的动态影响。建立了一维空调系统仿真模型,通过构建数据交换及仿真流程,实现了三维舱室与一维空调系统的联合动态仿真计算。与试验结果进行了对比分析,结果表明,联合仿真方法计算得到的舱室热环境动态响应曲线与试验结果一致性更好,能够更为准确地映出其动态变化特性。The traditional CFD simulation method of cabin thermal environment usually only considers the airflow structure of the fluid domain in the cabin,ignoring the influence of the solid domain.The dynamic response of the air conditioning system is ignored by the constant air supply boundary condition,which results in the inability to accurately simulate the dynamic change of the cabin thermal environment.Therefore,a three-dimensional physical model of cabin and passenger is established for a special vehicle.By means of fluid-structure coupling and boundary condition modification,the cabin wall and the solid area in the cabin were treated respectively,and the dynamic influence of the solid area on the cabin thermal environment was considered.The simulation model of one-dimensional air conditioning system is established,and the joint dynamic simulation calculation of three-dimensional cabin and one-dimensional air conditioning system is realized by constructing data exchange and simulation flow.Compared with the experimental results,the results show that the dynamic response curve of the cabin thermal environment calculated by the co-simulation method is in better agreement with the experimental results,and can reflect the dynamic change characteristics more accurately.
