As wind turbines are increasingly deployed near residential areas, noise reduction is becoming a design constraint rather than a secondary consideration. The blog by Steve Mulski and Wouter Van Der Velden presents a comprehensive simulation framework built on the Dassault Systemes 3DEXPERIENCE® platform, integrating design, structural, and acoustic analysis.
It identifies two primary noise sources:
- Broadband aero-acoustic noise from blade–air interaction
- Tonal vibro-acoustic noise from drivetrain components
The framework combines multiple tools across workflows:
- CATIA® supports blade geometry design and modifications
- SIMULIA® and PowerFLOW® is used for aero-acoustic simulations to study airflow and noise generation
- Simpack™ models multibody dynamics of the drivetrain
- Abaqus® provides structural simulation inputs
- Wave6® enables acoustic propagation and noise radiation analysis
By connecting these tools within a unified environment, the approach aims to provide a system-level understanding of noise behavior, support design evaluation, and assist in meeting evolving regulatory requirements for wind turbine installations.
