Problems solved by technology
Traditional design methods are time-consuming and inefficient, and have the following problems:
[0004] (1) It needs to be carried out in series from design to performance analysis, and the performance analysis can only be carried out after the design is completed, and the two cannot be carried out simultaneously;
[0005] (2) Redesign without synchronous performance analysis as a reference, often has a lot of blindness, and cannot reflect the requirements of product performance;
[0006] (3) It is difficult to directly generate conceptual design from performance analysis results, and it takes multiple cycles to reach the standard

Embodiment Construction
[0024] The invention discloses a method for optimal design of an automobile body, which comprises the following steps:
[0025] The first step is to read in the body shape reference data before the optimization design, such as figure 1 As shown, for example, the body shape reference data of the previous model is read.
[0026] The second step is to capture the characteristic lines in the body shape reference data before the optimization design, and the characteristic lines refer to the curves surrounding the vehicle structure surface. figure 1 In the body shape reference data shown, the characteristic lines are as follows figure 2 shown.
[0027] The third step is to transform the body shape reference data before optimal design on the basis of feature lines to form a control module, that is, to generate line grids through feature lines, and to form surface grids from line grids by scanning or dragging in the view plane , and then scan or drag the surface grid in the dire...

The invention discloses an optimal design method for an automotive body. The optimal design for the automotive body is finished by extracting a characteristic line of the current automotive type, generating a control module according to the characteristic line, connecting the control module and data of the original automotive type, modifying the control module according to a design requirement and adjusting the characteristic line of the automotive type. By the optimal design method, the optimal design for the automotive body by a user can be facilitated greatly, the design efficiency can be improved and the design cost can be reduced.
Description
technical field [0001] The invention relates to an optimal design method of an automobile body. Background technique [0002] In order to develop the synchronous research and development capabilities of the preliminary engineering projects of automobiles, aerospace, aviation, ships, heavy industry machinery, etc., a method that can be used in the basic data (CAD, CAE, CAS, these three data are used in the same physical coordinates) The data describing the physical characteristics of the same designed product, CAD data is used to describe the geometric characteristics of the designed product; CAE data is the grid data generated based on CAD data, which is used to analyze and evaluate the structural performance; CAS data is used to describe the modeling characteristics in the modeling design The curves and surfaces) are deformed on the basis of rapid acquisition of software that can be used for CAE concept analysis and CAD design analysis. In order to achieve this, it is nece...
