Experience
Dev Research Engineer 2
Jan 2023 — Present · Peoria, IL, US
Conducted torsional vibration analysis on powertrain systems for a variety of heavy machinery (trucks, tractors, excavators), using simulation to prevent driveline failures and improve durability.• Built and analyzed detailed 1D mass-elastic models to assess and optimize driveline behavior under different load conditions.• Performed FEA using Creo Simulate to calculate stiffness in critical components such as driveshafts, gears, and hubs, aiding in accurate NVH prediction.• Validated simulation models using raw field test data, improving prediction accuracy and enabling early detection of potential failure points.• Developed and refined custom simulation tools for internal use, improving model correlation and reducing analysis time for test case validation.• Collaborated cross-functionally with design, testing, and systems teams to integrate simulation feedback into product development cycles.• Created an innovative methodology to tune cylinder pressure and engine load, enhancing component robustness and performance.• Simulated multi-powertrain configurations (electric, gas, and diesel), assessing drivetrain component risk under various operational environments.• Resolved CPI (Continuous Product Improvement) and NPI (New Product Introduction) issues for global teams, reducing downtime and improving reliability.• Supported vehicle testing operations by assisting with instrumentation planning, data acquisition, and on-site troubleshooting of powertrain systems.
