We are delighted to offer you this presentation held by Colin Schwarz from GE Renewable Energy at the 5th Wind & Drivetrain Conference on April 6, 2022.
In his current role, @CS provides simulation-based risk assessment on narrow banded machinery noise with a strong focus on gearbox tonality. Together with colleagues, Colin sets up and validates processes based on multibody simulation, which supports such an assessment. Before joining GE Renewable Energies, Colin spent almost five years on the Simpack team of Dassault Systèmes and covered topics like customer and project support, training, and product management. In parallel, Colin has been working on sophisticated wind turbine controllers, also called model predictive control.
Besides real-time capabilities to provide a feasible control signal in time, topics like the controller impact on the drive train fatigue strength need to be adequately addressed.
Colin is a member of the SIMULIA Champions program.
Abstract:
The noise emission of wind turbines and farms can be an important and limiting factor for the acceptance and thus further growth of wind energy. Next to the overall noise emission level, tonal noise from machinery and drivetrain components can be disturbing contributions.
This presentation discusses the modeling of tonal noise contributions originated by gearbox teeth meshing, transmitted through complex, structure-borne transfer paths into the machine head, and radiated by tower and blade surfaces. A seamless tool-chain of multibody simulation and boundary element method to solve the wave equation is a core feature to integrate such an approach for risk assessment and analysis into established design processes. Its reliability and uncertainty need to be understood very well to drive design decisions early in the design phases.
