摘要
为了提高机床的承力刚度,用有限元方法来研究了重型混联机床XNZH 2430的静刚度,在UG NX 2.0和AN-SY S 8.0的环境中分别建立了该机床的三维实体模型和有限元模型。计算了该机床在不同位形时承受一定载荷引起的变形位移。计算结果表明,该构型混联机床的x方向刚度较差,是薄弱环节;y方向和z方向刚度较好。为有效提高机床的x方向刚度,对机床某些部件的结构进行了改进。研究结果为该机床的设计和优化提供了依据。
The stiffness of a heavy hybrid machine tool named XNZH2430 was analysed using the finite element analysis method. The three-dimensional solid model was built using the CAD software UG NX 2.0 with the finite element analysis clone in ANSYS 8.0. The machine tool stiffnesses were computed for various configurations with the results indicating that the stiffnesses along the y and z direction are better while that along the x direction is worse. The stiffness along the x direction of the machine tool was improved by modifying the component structures. The results can be used to optimize machine tool designs.
