摘要
为保证车辆安全性,提高减振器弹簧托盘强度,利用ARIZ算法对其进行了优化设计。基于ARIZ算法对减振器系统进行功能分析并建模,分析问题模型定义技术矛盾,定义理想解确定物理冲突,建立SLP模型和资源分析,生成多个解决方案。通过理想化水平公式分析评价,得到最优解。利用CATIA软件建立弹簧托盘模型,并进行有限元仿真分析,分别得到优化前后托盘的位移和应力云图,对优化后滑柱总成进行耐久试验验证。结果表明:优化后的托盘位移形变量小,应力分散,最大处应力值小,满足耐久试验要求,可为后续相关研究提供参考。
In order to ensure vehicle safely and improve the strength of shock absorber spring tray,ARIZ algorithm is used to optimize the design.Function analysis and modeling of shock absorber system are carried out using ARIZ algorithm.The problem model is analyzed and the technical contradiction is defined.The ideal solution is defined and physical conflicts are identified.The SLP model is built and resource analysis is performed,and multiple solutions are generated.Spring seat model is created in CATIA software and finite element simulation is perfomed,and the displacement and stress map of the pallet before and after optimization are obtained.the durability test of the optimized strut assembly is carried out.The results show thathe optimized pallet displacement is small,stress is dispersed,and the maximum stress is small,which satisfies the requirements of durability test.The proposed method can provide reference for the follow-up research.
