摘要
采用有限元软件ANSYS计算分析了专用数控管螺纹加工车床主轴箱的应力分布、变形、固有频率及振型。分析结果表面,专用数控管子床的主轴箱结构抵抗破坏的能力较大。通过分析主轴箱的固有频率和振型,对主轴箱结构的薄弱环节提出了改进方案。
In this paper,calculation analysis of the stress distributions,inherent frequencies and mode shapes in spindle box of a special NC boring-milling machine based on ANSYS are introduced.The result shows that the box has much ability in resisting the force from spoiling.The inherent frequency and vibration type is analyzed and the improving program for its weakness is proposed.
