Abstract

The invention discloses a CAE analogue simulation method for an automobile active air inlet grille, and belongs to the technical field of automobile design, and the CAE analogue simulation method for the automobile active air inlet grille comprises the following steps: determining a CAE analogue simulation analysis working condition of the automobile active air inlet grille; establishing a finite element model of the automobile active air-inlet grille by adopting an unequal thickness modeling method; an automobile active air-inlet grille system is built, and material attributes are established; and S2, carrying out working condition simulation and simulation analysis by using CAE software according to the CAE simulation analysis working condition determined in the step S1. The development cycle of the automobile active air inlet grille can be shortened, and the development cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobile design, in particular to a CAE simulation method for active air intake grilles of automobiles. Background technique [0002] The active air intake grille of the car is located directly in front of the front of the car, and its main function is to provide the two functions of air intake and heat dissipation for the engine. The active air intake grille of the car can control the air intake volume and wind resistance by changing the opening and closing of the air intake grille, thereby improving fuel economy and allowing the engine to quickly reach the optimal operating temperature. [0003] When designing automobile active air intake grille, the material of automobile active air intake grille is mainly plastic material, and its performance is mainly verified through experiments at present. When testing and verifying the performance of automobile active air intake grille, it is often necessary to...
