Abstract

The invention provides and discloses a simulation method and a simulation device of a passenger compartment refrigeration effect. The method comprises the following steps: reading the three-dimensional graph of a passenger compartment and the three-dimensional graph of a human body in the passenger compartment; executing surface mesh division on the passenger compartment and the surface of the human body; repeatedly repairing the mesh quality of surface meshes; on the basis of the repaired surface mesh, dividing space in the passenger compartment into volume meshes; calling a fluid physical model, and loading the three-dimensional graph of the passenger compartment, the three-dimensional graph of the human body in the passenger compartment, and the volume meshes formed by the division of unfilled space into the fluid physical model; setting a fluid boundary condition, and calculating and outputting fluid performance parameters of volume meshes according to the fluid boundary condition. According to the simulation method, an airflow movement direction in the passenger compartment, the airflow speed of the human body surface, the distribution situation of airflow on the human body surface and the like can be obtained for evaluating whether the refrigeration effect of the passenger compartment conforms to the standard of the comfort level of the passenger compartment. Time is saved, manpower and financial resource consumption can be reduced, and cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and device for simulating the cooling effect of a passenger compartment. Background technique [0002] The passenger compartment of a car is a relatively closed space, and the driver needs to stay in the passenger compartment for a long time. When the thermal comfort in the passenger compartment is poor, the driver is prone to trance and inattention after driving for a long time. Driving safety hazard. [0003] When the driver is driving a car, it is necessary to improve the thermal comfort of the passenger compartment, so as to improve the driver's physical and mental comfort during driving and ensure driving safety. Therefore, the comfort of the passenger compartment is an important factor restricting driving safety. The problem. [0004] In the prior art, the analysis of the comfort of the passenger compartment directly conducts the transient analysis of the tem...
