摘要
对CA6140车床的三支承主轴优化设计过程进行了论述,为进行有限元分析建立更加准确的模型,以减少有限元的分析次数和计算量。以主轴结构的重量最轻为目标函数,较完整地给出了数学模型的建立过程,采用SUMT惩罚函数内点法求解,运用MATLAB优化工具箱对三支承机床的主轴进行优化设计。与传统设计方法得到的结果相比,所得的主轴体积减小约19.2%,为优化方法结合有限元法进行机床的动态设计、性能改进提供了一定的理论依据。
Optimum design of CA6140 machine tool spindle with three bearings is carried out.A more accurate model for finite element analysis is established to reduce the analysis times and the computation load.The objective function bases on minimum weight of spindle.The process of setting mathematical model is described in detail and the SUMT solution method is adopted.Based on MATLAB optimal toolbox the optimum design of machine tool spindle was carried out.Compared with the result by traditional design methods,the optimum spindle’s volume reduces by 19.2%.It provides a theoretical basis for dynamic designing and optimizing function with optimization and finite element method.
