Problems solved by technology

[0004] Due to the professional complexity of subject simulation, various simulation analysis software are scattered in various majors and operated by a small number of design and simulation personnel. Knowledge and experience are scattered among individuals, which is difficult to accumulate and share, which is not conducive to the accumulation of enterprise knowledge and the formation of expert knowledge base.

Embodiment Construction

[0038] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing

[0039] 1. The geometric processing function module can be divided into several different types of problems according to the object of geometric processing (car body or bogie), vehicle type and design stage, and the input conditions are in brackets:

[0040] Spot welding car body (body geometric solid model + 2D welding spot)

[0041] Seam-welded car body (body geometric solid model + joint joint seam welding)

[0042] Pre-designed car body (2D section + 2D car body model)

[0043] bogie model

[0044] Develop different modeling processes for the above-mentioned different types, and accordingly develop the geometric pre-processing function module into a template set with multiple branches to choose from. Although different types of models require different processing methods, the purpose of this step is to prepare 2D and 3D geometric models for...

Abstract

The invention relates to a preprocessing template for a vehicle model. The preprocessing template for the vehicle model consists of a geometric parameterized module, a naming standardization and material property automatic setting module, a grid partitioning module and a boundary condition module which are connected in sequence. Vehicles under research and development involve different vehicles such as railway locomotives, passenger cars, trucks, motor train units, urban rails and railways, the establishment of a general preprocessing template for a railway vehicle CAE (Computer Aided Engineering) model is particularly important. By developing the general preprocessing template for the general CAE model, complex preprocessing work in simulated analysis can be standardized and normalized. By means of a flow automation tool, the working efficiency can be increased while standard processing is realized, human errors are reduced, the CAE simulation preprocessing knowledge and experience of enterprises are accumulated and solidified, and the CAE simulation technology organization process capitals of enterprises are well accumulated and extended.

Description

technical field [0001] The invention relates to a vehicle model pre-processing template, especially for the simulation analysis of aluminum alloy car body, stainless steel spot welding car body, stainless steel laser welding car body and bogie. The template encapsulates the vehicle analysis process and specifications, and its function and simulation analysis corresponding to the steps of the process. According to the interactive operation provided by the simulation template, the whole process of vehicle model simulation analysis can be completed. Background technique [0002] Judging from the development trend of modern manufacturing industry, computer simulation technology will play an increasingly important role in the development of new products. Compared with traditional research and development methods, modern research and development methods combined with computer simulation technology can save a lot of manpower, material resources, and financial resources and greatly...
