【摘要】 利用大型有限元分析软件ANSYS对东北大学研制的3-TPT并联机床在某一工作位置的三种不同受力情况下的机床主体结构进行了线性静态分析,得出了该机床的刚度和应力分布情况,其分析结果和实际情况基本吻合,为机床的局部改进和后续的优化提供了依据。更多还原

【Abstract】 This paper processes linear static finit e element analysis for the 3-TPT parallel kinematical machine of Northeastern Un iversity by large-scale finite element analysis software, and gets the distribut ing result of stiffness and stress. The result accords to the actual situation; it puts forward the basis for improving part of the machine tool and subsequent optimizing.更多还原
