A Wind Turbine Drivetrain Diagnostics Simulator (WTDS) generates wind-turbine-drivetrain faults so users can learn to recognize signatures in a controlled environment. The setup lets users learn signatures of drivetrain component faults such as gear surface wear, cracks, chips, and missing teeth. By sharpening the skills of client analysts, the bench-top system, can minimize gearbox, bearings, and blade-mechanism failures thereby avoiding unexpected downtime and production loss. The system also shows bearing inner and outer race defects and bearing ball damage. And it shows signatures for gear backlash, eccentricity, and misalignment.
Distinguishing and recognizing drivetrain faults result in quicker field diagnostics and repair. The complete drivetrain consists of a two-stage planetary gearbox, a two-stage parallel-shaft gearbox with rolling or sleeve bearings, a bearing loader, a programmable magnetic brake, and a variable yaw-and-pitch scaled wind turbine. All elements of the WTDS maximize the number of drivetrain configurations to research gearbox dynamics and acoustic behavior by health monitoring, vibration-based diagnostic techniques, lubricant conditioning, or wear-particle analysis. It is rugged enough to handle heady loads and spacious enough for easy gear placement, setup, and installation of monitoring devices.
