Effects of Uncertain Parameters on the Dynamic Response of a Wind Turbine Gearbox

Year: 2026

Type: article

Abstract: Producing reliable gear systems for wind turbines involves accounting for multiple uncertain parameters. To ensure operational vibrations remain controlled, it is essential to analyze the system’s sensitivity to these uncertainties. This study investigates the dynamic response of a two-stage wind turbine gear system, considering variations in many system variables. The goal is to evaluate the system’s reliability through bearing displacement analysis. A 12-DOF concentrated-parameter model is proposed to account for uncertainties in gear mass, damping, and the inertias of the pinion, gear, and input shaft. The dynamic response is examined using the Polynomial Chaos (PC) method across different orders and standard deviations, with results validated through the Monte Carlo (MC) method using 100,000 samples.
