Embodiment

[0074] 1. Calculation process of force deformation analysis of machine cover outer plate structure:

[0075] 1. Preprocessing and meshing:

[0076] UG NASTRAN advanced simulation module is used for pre-processing and grid division of the press and mold, and at the same time, the material parameters of each part of the model are input into the analysis model.

[0077] 2. CAE analysis of structural deformation:

[0078] The solver uses ABAQUS 6.7.

[0079] a. import model

[0080] b. Define analysis steps

[0081] Three analysis steps are used to gradually guide the model solution process to achieve correct analysis results.

[0082] c. Define contact properties

[0083] Using the Mechanical (mechanical) analysis option, select Tangential Behavior (tangential properties), Normal Behavior (normal properties) and Geometric Properties (geometric properties). For the setting of the normal attribute, the constraint enhancement method selects Augmented Lagrange, and the frict...

Abstract

The invention relates to the technical field of die processing, in particular to a making method of a digital die model. The method includes the steps of 1, building a machine tool model at 1:1 through field data; 2, building an analytical model; 3, acquiring model data and boundary condition data of dies; 4, determining initial contact area data through the acquired boundary condition data and the optimized data of contact parameter and field data; 5, through the computed initial contact area data and theoretical data, verifying data compared to the field data so as to verify simulation results; 6, quantitatively analyzing simulation result data; 7, based on data acquired by die deformation and die face compensation computation, performing modelling to obtain a finished product. Compared with the prior art, the making method has the advantage that experimental theories are improved via the field data of actual dies by means of physical simulation experiments and numerical simulation techniques.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a method for making a digital mold model. Background technique [0002] The automobile industry is a pillar industry in Shanghai. As a priority support and key development object, it is highly valued by the government. With the continuous increase of the annual output of automobiles, advanced technical equipment for manufacturing automobiles is indispensable, and as an important equipment in the manufacture of advanced technical equipment for automobiles, automobile panel molds have a direct relationship with the design and manufacturing cycle and level of new automobile models. The development cycle and time to market are particularly important. [0003] In 2005, the Chinese government promulgated the "Administrative Measures for the Import of Auto Parts Constituting the Characteristics of Complete Vehicles", requiring vehicle manufacturers to increase the local procure...
