摘要
采用了理论设计和有限元仿真分析相结合的方法,设计了基于液体静压导轨的大行程快刀伺服系统(最大加工行程30mm,行程4mm时频响不低于50Hz)。首先,设计得到了基于液体静压导轨的大行程快刀伺服系统的结构模型和相关参数;接着,利用ANSYS/FLUENT软件对液体静压导轨的变形、模态以及油膜压力分布进行仿真分析,并且将油膜刚度的理论计算值和仿真计算值进行比较,验证了导轨设计的可靠性;最后,选用能够满足要求的音圈电机、位置反馈装置以及功能强大的MPAC运动控制器等完成了控制系统的搭建。
Combining theoretical design and finite element simulation, A large stroke fast tool servo system based on hydrostatic guideway（maximum processing stroke 30 mm, not less than 50 Hz frequency response when stroke 4mm） was designed. The structure model and related parameters of hydrostatic guide rail are obtained through theoretical design. The software ANSYS/FLUENT is used to analysis the hydrostatic slideway deformation, modal and oil film pressure distribution, the theoretical calculation of oil film stiffness and simulation results of oil film stiffness are compared, which verify the reliability of the design. The voice coil motor, position feedback device and powerful MPAC motion controller which can meet the design requirements are used to build the system.
