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.
