- DNV GL/IEC 61400 certification experience preferred. Core Technology R&D
1. Lead the structural design, mechanical modeling, and dynamic performance optimization of
three-row cylindrical roller main bearings, focusing on breakthroughs for large-capacity
(6MW+) wind turbines under high-load and long-life technical challenges. Address reliability
issues under high dynamic loads (e.g. wind load fluctuations, start-stop impacts) and
extreme conditions (-30°C low temperature, salt spray corrosion, high humidity).
2. Optimize internal load distribution and roller contact stress to enhance fatigue life (target
≥25 years) and reduce LCOE (Leveling Cost of Energy).
3. Simulation of bearing contact stresses, fatigue life, and failure mode studies using
multi-body dynamics (MBD) and finite element analysis (FEA). Apply multi-physics
simulation tools (such as Romax Wind Turbine and ANSYS Workbench) to analyze bearing
dynamic characteristics, perform thermal-mechanical coupling analysis, and predict failures.
4. Lead Bearing-Gearbox-Spindle System Integration Compatibility Analysis to resolve systemic
engineering issues such as vibration noise and lubrication failure.
5. Responsible for mechanical simulation analysis of triple-row pillar bearings (static/dynamic
load distribution, fatigue life prediction), optimizing bearing parameters (roller profiling, preload, clearance design) based on the overall machine load spectrum.
Test Validation System Construction
1. Design a full-scale bearing test rig programs (including ultimate load and accelerated life
testing), and establish a correlation mechanism linking test data with simulation models.
2. Lead Root Cause Analysis (RCA) of Dominant Wind Field Failure Cases, Iterative Optimization
of Design Specifications and Process Standards. .
Cutting-Edge Technology Research
- Explore innovative approaches such as segmented designs for ultra-large bearings and intelligent condition monitoring, while establishing patent barriers.
- Monitor updates to international standards such as IEC 61400 and DNV GL to promote product certification and global technical compliance. .
Manufacturing & Quality Control
- Lead the development of manufacturing processes for ultra-large wind turbine bearings (outer diameter ≥ 3 meters), overcoming technical challenges including ring deformation control, precision grinding of raceways, and surface strengthening (gradient control of carburizing/nitriding). .
- Establish a comprehensive quality inspection system covering the entire bearing life-cycle, and develop standards for critical processes including non-destructive testing (ultrasonic and magnetic particle inspection), residual stress testing, and microstructure analysis (SEM/EDS).
Standardization&Cutting-Edge Innovation
- Lead or participate in the wind turbine bearing industry, ensuring designs comply with international standards such as IEC 61400-4 and DNVGL-ST-0376.
- Preliminary research on innovative materials (high-purity bearing steel, ceramic coatings) and intelligent technologies (embedded sensors, digital twin predictive maintenance).
