specific Embodiment approach 1

[0021] Specific embodiment one: a kind of automobile instrument structure optimization method based on Moldflow analysis comprises the following steps:

[0022] Step 1: establish an automobile instrument structure model for the automobile instrument structure through CATIA software;

[0023] Step 2: Import the model established in Step 1 into CADdoctor for diagnosis;

[0024] Step 3: Repair the model according to the diagnosis result obtained in Step 2;

[0025] Step 4: Import the repaired model in Step 3 into CADdoctor for diagnosis;

[0026] Step 5: Repeat Step 3 to Step 4 until there is no error message, then execute Step 6;

[0027] Step 6: Open Autodesk Simulation Moldflow Synergy (mold flow analysis software) and import the file generated in Step 5 into Autodesk Simulation Moldflow Synergy, click the mesh division command to perform double-layer mesh division and grid statistics, and according to the grid division The results of mesh repair;

[0028] Step 7: Set the ...

specific Embodiment approach 2

[0035] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the specific process of repairing the model according to the diagnosis result obtained in Step 2 in Step 3 is as follows:

[0036] According to the diagnosis result obtained in step 2, click the automatic repair function button in the function area of ​​CADdoctor to automatically repair the sharp corners, broken surfaces, incomplete surfaces, rounded corners smaller than R3 and prominent text in the model. For those that cannot be automatically repaired Sharp corners, broken surfaces, incomplete curved surfaces, rounded corners smaller than R3 (radius 3mm), and prominent text After saving the model, open the CATIA software for manual model repair.

[0037] Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0038] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the error information in step 5 includes broken surfaces, geometric loss and free edges.

[0039] Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses a Moldflow analysis-based automobile instrument structure optimization method, relates to an automobile instrument structure optimization method, and solves the problems of high design cost and low production efficiency due to experience-based design in conventional structure design. The method comprises the steps of building a model for an automobile instrument structure through CATIA software, importing the model to CADdoctor for performing diagnosis and repair, and importing the repaired model to the CADdoctor for performing diagnosis; and performing dual-layer meshdivision and mesh statistics, performing mesh repair according to a mesh division result, setting analysis contents in a filling dialog box, selecting materials and a plate number in a material dialogbox, setting a pouring system, clicking start for analysis, generating an analysis report, modifying the model in the CATIA according to the analysis report, and re-diagnosing the modified model, until a non-defective automobile instrument structure model is obtained. The method is used in the field of automobile instrument structure optimization.

Description

technical field [0001] The invention relates to an automobile instrument structure optimization method based on Moldflow analysis. Background technique [0002] The structural design of automobile instruments is mostly plastic injection molding products. In the traditional structural design, the design is mostly based on experience, which leads to some unreasonable structural designs, which lead to multiple revisions of the mold, which affects the development cycle and increases the design cost. Reduced production efficiency. Moldflow analysis software is a high-speed and effective design analysis software. It can not only quickly identify model errors, but also quickly and effectively predict product design defects and injection molding defects in advance, thus providing designers with a fast and reliable design reference. The design process is continuously accelerated, and the design cost is greatly reduced. Contents of the invention [0003] The purpose of the present...
