Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0011] The realization method of the computer-aided car chassis general arrangement of this utilization three-dimensional CAD and secondary development technology thereof of the present invention, its steps are as follows:

[0012] 1. Establish a 3D parametric model library of the car chassis assembly

[0013] Extract the overall parameters of each component, that is, the basic structural parameters related to the general layout, such as the length, width, height and other dimensions that characterize the outline of the component, the positioning reference of the component, etc. The simplified model of the parts is controlled by these overall parameters, and the variable and parametric design is carried out. During chassis assembly, rapid layout of auto parts and dynamic modification of basic structural dimensions can be realized by modifying corresponding pa...

Abstract

The method includes the following steps: 1. establishing 3D parameter model library of sedan chassis assembly via extracting the overall parameters of the parts, controlling the simplified model and variable and parameter design to realize the fast layout of sedan parts and the dynamic amending of basic structure sizes through amending corresponding parameters during assembling chassis; 2. determining the tree structure for sedan chassis assembling; and 3. determining the sedan chassis assembly assembling mode via organizing the overall chassis structure in from-top-to-bottom design mode and assembling parts in coordination point mode. The present invention can support and guide design well and raise the overall quality of sedan chassis product.

Description

Technical field [0001] The invention relates to the technical field of three-dimensional CAD and its secondary development in computer technology, and mainly relates to a computer-aided method for realizing the general layout of a car chassis by using the three-dimensional CAD and its secondary development technology. Background technique [0002] At present, modern automobile design methods represented by CAD / CAE / CAM are gradually replacing traditional design methods. CAD in 3D can effectively overcome the disadvantages that the geometric relationship and motion relationship of parts cannot be clearly and intuitively expressed in 2D. The product development cycle is generally shortened and the design quality is greatly improved. The successful application of traditional CAD technology in product design, which is mainly characterized by algorithm-based structural performance analysis and computer-aided drawing, has caused a profound change in the design field. However, pure...
