| 摘 要： | 为了减少超精密机床中液体静压导轨热变形对机床加工精度的影响,本文建立了液体静压导轨动导轨有限元模型,利用有限元分析软件ANSYS对动导轨在不同工作环境下做不同运动时的热变形进行仿真分析,仿真结果表明,当动导轨做高速变加速运动时,动导轨热变形较大,会对加工精度产生较大影响,为此,提出了降低液体静压导轨热变形的方法.

| Abstract: | To reduce the influence of thermal deformation of hydrostatic guide to the lathe,the finite model of moving guide of hydrostatic guide is established,the thermal characteristics of moving guide under different working conditions are analyzed by using software ANSYS.The simulation results show that the thermal deformation of moving guide is big when it is doing high-speed variation acceleration motion.The methods of reducing thermal deformation of hydrostatic guide are proposed. |
