Wind Load Modeling
- 1. © 2016 Sentient Science Corporation – Confidential & Proprietary Title: Wind Load Modeling Presenter: Dr. Adrijan Ribaric
- 2. © 2016 Sentient Science Corporation – Confidential & Proprietary Sentient Science Materials Science Differentiation 1. Asset Management for Operators 2. Computational Testing & Reconfiguration for Suppliers ☑ Life Extension☑ Root Causes☑ Predict Earlier Key Industries Served WIND ENERGY • 22,000 assets under contract globally AEROSPACE • Rotorcraft, Fixed Wing, & Defense • (15 Years of R&D) RAIL • Wheel Rail Interface • New Market for Sentient Sentient Science is a trusted third party enabling life extension of rotating equipment through a digital platform, connecting operators and suppliers through asset actions that lowers the cost of energy.
- 3. © 2016 Sentient Science Corporation – Confidential & Proprietary What's New at Sentient Science? 1. New Product: DigitalClone Bearing available beginning of 2018 as part of our strategy to enable suppliers to create their own DigitalClone life models 2. We have Business Value Assessments (BVA) to share on how operators are reducing costs with DigitalClone Live 3. We have 2 digitalization panel sessions at the booth 1. Tuesday & Wednesday at 13:00 4. We have a jazz band and party Tuesday night starting at 16:00 5. Do you like scotch? Drop your card to win €400 bottle of scotch

Wind Loads are captured on a wind farm level basis, not turbine by turbine basis 2. Used in design stage, not during operation 3. Majority of SCADA is under-utilized and not properly curated Using DigitalClone: • Understanding loads and reliability on an asset basis • Replaces the needs for statistical models build out of field failure data

Editor's Notes
- 1- We computational model rotating components to understand the life through a material science based approach 2- this allows us to understand prior to failure where a crack is occurring and provide our customers with asset actions to extend the life of their machines 3- Different industries 4- Supplier vs. operator side Crack initiation (lower left) -> life extension (upper left) -> 3 markets
- Our Turbine model simulates the interaction between wind and elastic turbine structures
- Our Turbine model simulates the interaction between wind and elastic turbine structures
- Although drivetrain loads are experienced from the rotor, generator, and mechanical brake, let’s focus on the loads originated from the rotor in this slide, for simplicity purposes.
