基于ANSYS的数控铣床主轴箱优化设计

Optimization Design on ANSYS in Spindle Box of NC Milling Machine

运用工程软件ANSYS的优化设计模块,根据主轴箱的实际工况及机床零件加工精度要求,在参数化建模及结构应力分析基础上,对XK713数控铣床轴箱结构以减轻重量为目标进行优化设计。通过优化设计及分析,主轴箱结构重量减轻了23.2%,三个方向上刚度和应力得到了合理的分布。

The paper uses the structural optimization design module of finite element of ANSYS, according to the spindle box＇s machine condition and precision, then based on parameter model and stress analysis, to optimize the structure for spindle box of XKT13 NC milling machine. The result shows that about 23.2% of its weight has been reduced, and its deformation and stress distribution have been reasonable in three dimensions.
