FEA & Structural Analysis.

• Developed system-level and detailed finite element models (GFEM/DFEM) for structural assessment of wind turbine primary components under operational and extreme load cases.
• Performed static and nonlinear analyses of structural behavior, including contact and joint interactions.
• Prepared CAD geometry for FEA by simplifying features and creating split surfaces and bodies for efficient setup.
• Conducted fatigue assessment with S-N and critical plane methods for multiaxial loading environments.
• Analyzed bolted connections and critical interfaces, producing reserve factors (RF) to support validation and certification activities.
• Performed modal analysis to determine the natural frequencies of the support structure and assess potential resonance with operating frequencies.
• Ran parametric studies to evaluate sensitivity of structural response to bearing pad stiffness variation.
• Collaborated with cross-functional team on coupled thermal-structural analysis, including bearing misalignment effects.
• Evaluated radial jack capacity for fluid-film bearings (FFB), defining lift requirements and clearances to support maintainability and pad replacement feasibility.
• Developing FEA validation models and participating in validation activities.

FEA Automation

• Integrated automated workflows for composite blade root modeling in ANSYS APDL environments.
• Standardized simulation workflows, including bolt stress post-processing and consistent plot orientation, to streamline review and comparison across cases.
• Developed ANSYS APDL automation to transfer temperature fields from ANSYS Fluent thermal analysis into structural models for coupled thermal-structural simulations.
• Developed automation scripts using Python, MATLAB, and ANSYS APDL to improve analysis efficiency and reduce manual effort.
