Abstract

The invention relates to a method for designing automobile body structure layout. The method comprises the following steps of: 1) initially setting the parameters of a new type automobile, 2) choosing the white automobile body finite element models having similar structures and sizes, or directly building a white automobile body finite element model, 3) generating a grid enveloped model according to the white automobile body finite element model, 4) generating a body grid model according to the grid enveloped model, 5) topologically optimizing and analyzing according to a target parameter based on the body grid model, 6) according to an analyzed result and drawing an automobile body material layout diagram, 7) designing conception according to the layout diagram, and 8) designing the layout structure in detail according to the data of the conception design, performing simulating analysis of strength, NVH and impact performance CAE and formability process analysis according to the data of the detailed design of the layout structure, and modifying so as to acquire a three-dimensional digitized product model fit for volume production. The automobile body structure layout has the advantages of shortened developing period and lowered researching and developing cost.

Description

technical field [0001] The invention relates to a computer-aided design technology applied in the field of automobile design, in particular to a computer-aided design method using a CAE software platform for vehicle body structure layout. Background technique [0002] The competition among auto companies is becoming more and more fierce, and the speed of car replacement is getting faster and faster, that is, the requirements for the R&D cycle of cars are getting shorter and shorter, and the R&D cycle and R&D costs are becoming more and more important to the automotive market. [0003] The traditional body structure layout is mainly based on determining the shape and opening parts, etc., and further layout is carried out according to experience and reference models, etc., and the comparative analysis results of various layout scheme data cannot be obtained, and the simulation and simulation can not be obtained. good plan. In the layout of some structural parts, it is difficu...
