摘　　要：运用APDL参数化语言对T2120深孔机床主轴结构进行优化设计。根据结构优化原理建立了主轴数学模型;运用APDL参数化语言建立了主轴有限元模型,将优化后的主轴与传统的设计相比较,主轴体积减少了9.1%,主轴单元最大变形只增加了4%,单元应力减少了23%,通过结构优化不仅减轻主轴重量,同时减小了单元应力,为该机床主轴的进一步参数化结构优化和性能改进提供了一定的理论依据。T2120 deep hole machine tool spindle structure is optimized by using the APDL parametric language. According to the structural optimization principle,the mathematical model of spindle is established; secondly,the finite element model of the spindle is established by using the APDL parametric language,the design of spindle after optimization is compared with the traditional design,spindle volume is decreased by 9.1%,the maximum deformation of spindle unit is only increased by 4%,unit stress is decreased by 23%,through optimizing the structure not only reduce spindle weight, but also reduce the unit stress,it provides certain theory basis for the further the parametric optimization of the machine tool spindle structure and performance improvement.
