Abstract
This study compares and analyzes key parameters of high-speed shaft couplings made from composite materials, focusing on the debonding area, the presence of pins, and the friction coefficient. High-speed shaft couplings are critical components of drivetrain systems, directly affecting the overall stability and reliability. Previous research has examined the design of high-speed couplings for a 6 MW wind turbine drivetrain. Building on this foundation, the present study evaluates the structural and mechanical performance of couplings under varying conditions. By systematically analyzing the effects of different debonding areas, the inclusion or exclusion of pins, and varying friction coefficients, this study aims to identify key factors influencing the coupling’s reliability and efficiency. The findings are expected to contribute to the development of high-performance couplings for large-scale wind turbines, enhancing durability, operational stability, and long-term reliability.

Keywords
