摘要

The invariants of rotational error motion are introduced and used to study the radial and axial errors of spindles. The actual motion of the rotor relative to the stator is described by its invariants; and then, the kinematic model for testing the radial and axial errors are established according to the measuring and evaluating principles. The relationships between the invariants and the proposed errors are set up by the model, and the kinematic properties of the errors are discussed. The spindle of a lathe is tested as an example, in which the actual motion of the rotor with six-DOFs in space are accurately considered. As a result, the intrinsic influences of different testing positions and directions are revealed.
