SENSITIVITY ANALYSIS FOR THE EFFECT OF MISALIGNMENTS ON PERFORMANCE PARAMETERS OF HARMONIC REDUCERS

The rise of Urban Air Mobility (UAM) heralds a new era in transportation, offering efficient and sustainable aerial solutions tailored for urban settings. Crucial to this evolution are compact electromechanical actuators (EMA), facilitating precise control of electric Vertical Take-Off and Landing (eVTOL) aircrafts components with agility and responsiveness. Compared to traditional hydraulic or pneumatic systems, EMA offer heightened efficiency, faster response times, and reduced maintenance needs, ideal for the UAM. At the core of rotary compact EMA lies the harmonic reducer, ensuring high reduction ratios with minimal backlash and robust torque transmission. Its role in maintaining precision and minimizing losses is vital for system efficiency and reliability. Reliability is paramount in UAM, necessitating redundancy measures and the adoption of Prognostics and Health Management (PHM) strategies. PHM integrates data-driven algorithms to predict component health, enabling proactive maintenance and mitigating failures. This paper delves into the impact of misalignment on harmonic reducer performance, aiming to enhance the reliability and efficiency of EMA systems in UAM. By analyzing reducer dynamics, it aims to contribute to the advancement of UAM technologies, fostering safer and more dependable urban air mobility systems.
