Development of a Simulation-Based Model for Accuracy Analysis of Optical Rotary Encoders Under Mechanical Vibrations

This is the latest version of this item.

This study presents the development of an innovative simulation-based model for analysing the accuracy of optical rotary encoders subjected to mechanical vibrations. The proposed approach establishes a digitally controlled environment that emulates real operational conditions, enabling systematic examination of dynamic effects on encoder performance. The model integrates essential components that allow the formation of a system capable of operating both within a digital simulation environment and under real experimental conditions with controlled generation of mechanical vibrations. By simulating diverse operating scenarios, the model provides detailed characterisation of measurement deviations and identifies variations in measurement error of the investigated encoder as a function of changes in input parameters. The resulting insights support predictive evaluation of measurement error behaviour and enable systematic assessment of encoder accuracy under varying vibration and operating conditions. Consequently, the proposed simulation method offers a reliable and reproducible tool for investigating vibration-induced measurement errors in advanced precision systems.
