Abstract

The invention discloses a CAE (Computer Aided Engineering) modeling method for improving the simulation precision of an automobile semi-axle, which belongs to the field of automobile research and development and manufacturing, and comprises the following specific steps of: obtaining the size and hardness of each heat treatment influence area of a semi-axle part, and determining a finite element grid of the semi-axle part according to the size of each heat treatment influence area of the semi-axle part; obtaining a semi-axis assembly finite element model, and determining material attribute dataof each heat treatment influence area of the semi-axis part according to the hardness of each heat treatment influence area of the semi-axis part; determining material attribute data of a finite element model of the half-shaft part through the material attribute data of each heat treatment influence area of the half-shaft part and the finite element grid of the half-shaft part; and obtaining boundary conditions and load conditions of the finite element model, and determining establishment of an automobile semi-axis CAE simulation analysis model. According to the method, the high-precision part stress state can be obtained through CAE simulation calculation, so that the high-precision key parameters of the strength and durability of the automobile semi-axle are obtained, and the method hasthe advantages of being high in adaptability and wide in application range.

Description

technical field [0001] The invention discloses a CAE modeling method for improving the simulation accuracy of an automobile half shaft, and belongs to the field of automobile research and development and manufacturing. Background technique [0002] As a key technology to predict the stress distribution, static strength and fatigue life of auto parts, CAE simulation analysis has been widely used in product development. The automobile half shaft is the part that connects the differential half shaft gear and the wheel hub. Compared with the CAE analysis of other transmission system assemblies such as automobile transmissions, the automobile half shaft has the characteristics of small number of parts and small assembly scale of the simulation model. High-precision simulation schemes can be used for simulation analysis conditions such as cell type and size, boundary conditions, etc. Therefore, the difference in material properties has become the most important factor affecting th...
