Abstract: The present invention provides a typical rotational part characterization method based on actually measured run-out data. Aiming at the characterization of rotational parts containing morphology data, the present invention proposes a matrix form characterization method in which microscopic run-out data and macroscopic axial size are comprehensively considered. In addition, the method can be applied to an assembly accuracy calculation process, and can characterize a single part containing morphology feature quantities by using only one matrix M. The calculation process of accuracy transfer is simplified, and a high-efficiency calculation model is provided for the prediction of assembly accuracy.
