Paper Abstract

Angle measurement is the basic problem of mechanical testing theory and technology. High-precision angle measuring sensor is the core component that is irreplaceable for scientific research, advanced manufacturing and test measurement. In this paper, for the long-term technical problems of difficult to suppress the shaft axis error of the circular grating angle measuring sensor, the size and precision are difficult to reconcile, a new concept of multi-grating angle measuring sensor is proposed, and the error of the sensor itself, installation error, electronic subdivision error, and multi-grating measurement are studied. The angle sensor suppresses the shafting error and establishes a simulation model. A multi-grating angle measuring sensor experimental system was built. The experimental results show that the angle error of the multi-grating angle measuring sensor is 134.32"". The proposal of multi-grating angle measuring sensor provides a new way for mechanical angle measurement theory and method.
