Design and Development of a Model for Accuracy Assessment and Measurement Error Quantification of Optical Rotary Encoders Under Vibration

This study presents the development and implementation of an innovative
model designed to evaluate the measurement errors of optical rotary
encoders subjected to mechanical vibrations. The methodological
framework involves the analysis of factors related to the accuracy and
stability of three commercial optical rotary encoders, with the objective of
quantifying measurement errors induced by vibrations. To obtain a more
profound understanding of the encoders’ behaviour under realistic
dynamic conditions, the results were processed in MATLAB, enabling an
advanced analysis of the system’s response to vibration. This approach
improves both the accuracy and reliability of the model, allowing for a
thorough assessment of encoder performance under varying vibration
disturbances. The designed and developed model within this study
represents a significant and original contribution to the field of optical
rotary encoder performance analysis under dynamic operating conditions,
with a particular emphasis on the impact of mechanical vibrations on
measurement accuracy and stability.
