- Abstract
- Thermal nut stiffness model of a ballscrew system is proposed through accurate thermal deformation analysis. Differential temperature distribution is estimated through the finite difference method (FDM). Preload change is computed through interference analysis between shaft and nut sections. Thermal nut stiffness is estimated according to assembly, load and heat transfer conditions.
