Abstract

The invention discloses a guide rail slider database building method aiming at machine tool finite element analysis. The method includes: extracting CAD (computer-aided design) model drive parameters and kinetic analysis parameters according to a supplier handbook, and building a database; building CAD parameterized models of corresponding guide rail slider components according to database drive parameters; extracting drive parameters from the database, using point, line and face commands of command stream language of finite element analysis software to build simplified equivalent models which are used for finite element analysis; extracting guide rail slider component finite element analysis parameters from the database through secondary development of CAD and CAE (computer-aided education) software, and using the command stream language of the finite element analysis software to load the finite element analysis parameters to guide rail slider auxiliary kinetic models. By the method, automatic building of guide rail slider component CAD and CAE models, simulation analysis knowledge integration and analyzing models is achieved during machine tool design, and support is provided for machine tool design and simulation analysis. In addition, the method is applicable to other mechanical structure design fields applying the guide rail slider components.

Description

technical field [0001] The invention relates to a method for establishing a database of a guide rail slide block of a machine tool. In particular, it relates to a method for establishing a guide rail slider database for finite element analysis of machine tools. Background technique [0002] The current machine tool slide block model has only simple geometric information, which is only used in the design stage of the machine tool; when performing finite element simulation analysis of the machine tool, it is necessary to manually set the analysis parameters such as material properties and joint surface parameters in the finite element software, which is cumbersome and cumbersome to operate. easy to make mistake. Machine tool designers spend a lot of time on repetitive work, resulting in waste of design resources, and have a great impact on the efficiency and stability of machine tool finite element analysis. Therefore, it is particularly important to establish a guideway sli...
