Optimization Of 7075 Aluminum Alloy Structure And Hardening Process Parameters Finite Element Analysis

Analysis and improvements are carried out based on computer-aided design (CAD) and computer-aided engineering (C AE) method for the forging of certain company. During analysis, the forging is three-dimensionally modeled according to its basic size using Solidworks. Then the three-dimensional model is import into HyperWorks for finite element mesh division, and finally imported mesh model into ABAQUS Software for further finite element analysis. After defining the whole quenching process, temperature and stress field analysis are made. The analysis and comparison results show that the forging improvement design is performed reasonably and effectively. The main research works include:1) Geometry model of the forging before and after improved design is constructed respectively, which is reasonably simplified with the premise of well reflecting the main mechanical properties.2) Finite element analysis model is constructed before and after improved design with definitions of material properties according to the actual quenching. Then temperature field analysis results are obtained as well as temperature cloud chart.3) According to the obtained temperature cloud chart and sequential coupling theory, the stress cloud chary are obtained, from which, the level of distribution of stress can be analyzed.According to the above analysis results, the effectiveness of constructed FEA model is proved. In addition, this presented work can also provide design reference for the following process optimization.
