introduction

YE6254 Rotor Dynamics Comprehensive Teaching Experiment System is an experimental teaching and research instrument designed for institutions of higher learning and scientific research institutes in the field of mechanics and mechanical specialty rotor dynamics and other related courses. It simulates various operating states and multiple fault types of rotating machinery by setting different rotation conditions and structural forms of the flexible rotor shaft system. Through the measurement and analysis system, it can complete many basic experiments of rotor dynamics, dynamic balance experiments and fault Diagnostic and analytical experiments. The hardware and software of the system are designed to be open, aiming to provide a multi-purpose, comprehensive system platform, and create good experimental and analytical conditions for targeted and in-depth research of personnel engaged in rotor dynamics teaching and research.
