-
Lead 1.5 years structural design/thermal analysis project, focusing on the thermal failure of bearing in high-speed rail.
-
Created thermal network analytical model to predict temperature rise and power generation based on Finite Element Theory.
-
Results in 5% temperature decrease at the most failed region, and 20% increase in life span.
-
Experince with: FEA Simulation, Structural/Thermal Modeling and Analysis, 3-D Modeling, Thermodynamics, Heat Transfer, Lubrication,, Tribology and Design for Manufacturability.
-
Softwares: FORTRAN, AutoCAD, Pro/E, Origin.
