中文摘要
复杂薄壁件主要采用多轴铣削成型,除切削力会引起局部变形外,残余应力则是引起整体变形的主要因素且难以避免。其加工中极易产生振动,通过切削力热对残余应力产生显著影响,然而切削振动等动态因素对残余应力的影响机理不清晰、参数离线规划控制残余应力的方法不能满足复杂薄壁件高精度加工需求。因此,本项目探究影响残余应力的未变形切削厚度等静态物理特征和切削振动等动态因素的关联关系,研究基于测量数据的动态因素敏感性分析,揭示动态因素对残余应力的作用机理,提出融合驱动的残余应力准确预测建模方法;探索复杂薄壁件结构特征和残余应力分布对零件整体变形的影响规律,应用群智能优化理论,提出面向整体变形优化的残余应力分布规划方法;研究主轴转速等可实时调整加工参数的自调整策略,提出基于数字孪生的残余应力自适应调控方法。通过满足残余应力分布来优化整体变形,提高零件加工精度,为复杂薄壁件高精度加工提供基础理论和创新技术。
英文摘要
The complex thin-walled parts are mainly formed by multi-axis milling. While the local deformation is mainly caused by cutting force, the residual stress is the main factor that causes the overall deformation and is inevitable. It is very easy to produce vibration in the milling of complex thin-walled parts. The generated cutting force and heat have a significant impact on the residual stress. However, the influence mechanism of dynamic factors like cutting vibration on the residual stress is not clear, and the off-line parameter planning method to control the residual stress cannot meet the requirements of the high-precision machining of complex thin-walled parts. Therefore, this project studies the relationship between the static physical characteristics like the uncut chip thickness which affect the residual stress and the dynamic factors like the cutting vibration. Then, the sensitivity analysis of the dynamic factors is explored based on the experimental results. By revealing the influence mechanism of the dynamic factors on the residual stress, the fusion-driven accurate prediction modelling method of the residual stress is proposed. The effect of structural characteristics and residual stress distribution of the complex thin-walled parts on the deformation induced by residual stress is explored. With the theory of swarm intelligent optimization, a residual stress distribution planning method for the overall deformation optimization is proposed. Based on the self-adjusting strategy of real-time adjustable machining parameters like spindle speed, an adaptive control method of residual stress based on digital twin is proposed. The machining accuracy of the parts is improved through optimizing the overall deformation of the parts by satisfying the residual stress distribution, which provide basic theory and innovative technology for the high precision machining of the complex thin-walled parts.
