摘要
铝合金一体化压铸技术是实现汽车轻量化的重要手段。本文采用结构优化、成型仿真技术、压铸工艺对减震塔进行“材料-结构-工艺”一体化设计制造。首先,结合大量设计经验,通过性能目标和材料选择及结构设计,确定减震塔的三维数据。随后,对减震塔进行性能分析确保满足性能目标,并根据所设计的模具结构进行温度场和速度场的成型制造模流分析,并提出优化措施。最后,对零件进行试制,总结问题并分析原因,提出解决方法,形成减震塔全流程开发过程。研究表明减震塔轻量率达到16.5%,并满足性能要求。该一体化设计方法具有可行性,为行业提供了全流程分析能力与实际生产经验,提升了制造商采用一体化压铸技术的信心。
Aluminum alloy integrated die-casting technology is an important means to achieve automotive lightweight.In this paper,structure optimization,molding simulation technology,die-casting technology are adopt-ed for"material-structure-process"integrated design and manufacture of shock tower.Firstly,combined with exten-sive design experience,the three-dimensional data of the shock tower is determined through performance objec-tives,material selection and structural design.Subsequently,the performance analysis of the shock tower is con-ducted to ensure that the performance objectives are met,and the mold flow analysis of the temperature and velocity fields is conducted based on the designed mold structure,and optimization measures are proposed.Finally,the parts trial production is carried out to conclude problems and analyze causes,and propose solutions to form the shock tower development process.The study shows that the weight reduction rate of the shock tower reaches 16.5%while meeting the requirements of various performance indexes.The integrated design method is feasible,provides the industry with the ability to analyze the whole process and actual production experience,and enhances the confi-dence of manufacturers in adopting integrated die-casting technology.
