초록
To verify previously developed nut stiffness model of a ballscrew, an experimental setup measuring the axial deformation and the stiffness of a ballscrew has been devised. Single-nut and double-nut ballscrews are tested under several load and assembly conditions. It is confirmed that experimental values are around 80% of the mathematical nut stiffness.
