Research on Non-Contact Measurement Method of the Radial Circular Run-out Error of the Shaft Parts

Abstract

At present, in view of a bridge shell axial parts artificially by dial indicator to measure the radial problem of low precision .This paper proposes to use a frequency domain three-point method of shaft parts’ non-contact laser measurement. It mainly includes the establishment of the design of the measurement model, the data collection, the data analysis and the data display system. The feasibility of the scheme is verified by a case. It’s a good technical support for the study of the radial circular run-out error of the shaft parts.
