- Responsible for thermal and fluid simulation development of 3-in-1 / multi-in-one electric drive systems (motor, inverter, reducer) for new energy vehicles, including steady-state and transient heat transfer, fluid flow, heat dissipation and lubrication analysis at both system and component levels.
- Carry out motor thermal simulation for water cooling, oil cooling, end spray cooling and hollow shaft cooling solutions. Verify winding and magnet temperature, evaluate permanent magnet demagnetization risk, and complete electromagnetic-thermal coupling simulation.
- Conduct thermal simulation for electric control power devices (IGBT/SiC), PCB and capacitors. Calculate junction temperature and thermal resistance, verify heat dissipation reliability under high-temperature and peak-load conditions, and support thermal design development of 800V high-voltage platforms.
- Perform lubrication and cooling simulation for reducers, analyze gear churning, bearing oil supply, two-phase flow splashing, pressure drop and flow distribution. Optimize lubrication and cooling structures to solve overheating and insufficient lubrication problems.
- Build 1D/3D thermal simulation models for electric drive systems, conduct 1D-3D co-simulation, match vehicle cooling loops, and complete thermal balance verification under CLTC, WLTC, continuous climbing and peak overload conditions.
- Participate in bench temperature rise tests, vehicle thermal balance tests and thermal shock tests. Calibrate simulation boundary conditions and model parameters based on test data to continuously improve simulation accuracy.
- Propose optimization solutions for structure, flow channel, oil and water circuit layout based on simulation results. Cooperate with structural, electromagnetic, electronic control and test teams to complete scheme review and implementation, and solve thermal management problems in R&D and mass production stages.
- Establish and improve the simulation system, formulate thermal simulation modeling specifications, boundary condition standards and evaluation criteria. Improve development efficiency through DOE multi-objective optimization and simulation automation, and deliver complete simulation reports.
- Track advanced thermal management technologies in the industry, and conduct simulation pre-research and scheme verification for innovative technologies.
