Human body sitting posture modeling method based on CATIA knowledge engineering

Abstract

The invention discloses a human body sitting posture modeling method based on CATIA knowledge engineering. The method includes the steps that S1, a human body sitting posture template is established,input information of the human body sitting posture template is designed, and output information of the human body sitting posture template is determined; S2, a calling environment of the human body sitting posture template is set up, and input conditions before the human body sitting posture template is called are determined; S3, the human body sitting posture template is called, and file parameter information of the human body sitting posture template are corrected and determined; S4, according to the human body sitting posture template, a human body sitting posture model is generated to perform design check until a design check result meets the requirements of laws and regulations. The human body sitting posture modeling method based on CATIA knowledge engineering is high in degree of matching with a human body sitting posture, the generality during drawing, modeling and verifying is improved, the human body sitting posture model can be conveniently re-established according to needs, in this way, design time is effectively shortened, and design cost is effectively lowered.

Description

technical field [0001] The invention belongs to the technical field of automobile design, and in particular relates to a human body sitting posture modeling method based on CATIA knowledge engineering. Background technique [0002] Modern and contemporary CAD technology has been widely used in the design of mechanical products. Existing software such as CATIA and UG use extensive modeling based on parametric design. On the basis of using parametric design, and through appropriate secondary development , which can encapsulate the product design modeling process to realize template-based modeling, which can effectively improve work efficiency and modeling quality. [0003] In the traditional human sitting posture modeling method, different products need to be modeled, and then checked after the model is built. However, if the product changes when using this method, it is necessary to redraw the human sitting posture magic heart, These redrawing processes, such as poor versati...

[0003] In the traditional human sitting posture modeling method, different products need to be modeled, and then checked after the model is built. However, if the product changes when using this method, it is necessary to redraw the human sitting posture magic heart, These repainting processes, such as poor versatility, take a lot of time and effort from the designer
