滚珠丝杠副热变形计算分析及可视化

摘 要：以传热学原理为基础，探讨温升对滚珠丝杠副的影响。首先确定热流密度系数及对流换热系数，然后借助有限元分析软件ANSYS，建立滚珠丝杠副的有限元模型，计算求解温度场及热变形。仿真云图显示：滚珠丝杠以1350r/min旋转时，其温升达到3.8℃，引起8.32?m的热变形。#br# 关 键 词：滚珠丝杠；热变形；有限元分析；仿真云图

Abstract: Base on the theory of heat transfer, this paper discusses the influence of temperature on ball-screw. Firstly, the coefficient of convective heat transfer was determined as well as the coefficient of heat flux. Then the finite element model of ball-screw was built by finite element software ANSYS. Steady temperature field and thermal deformation was also obtained in the same way. The nephogram of simulation revealed that when ball-screw spanned at a speed of about 1350 r/min, its temperature raised to 3.8℃ with a thermal deformation of 8.32 ?m.#br# Key words: ball-screw; thermal deformation; finite element analysis; nephogram of simulation

Steady temperature field and thermal deformation was also obtained in the same way.
