2020.09 - Current
- Axial flux motor
- Thermal design and CFD of cooling system for Axial flux motors (30 kw) which is capable of dissipating heat flux
- More than 50 W/cm2 by using ANSYS (and mathematical modeling of entire thermal system using octave and
- C programming)
- Complete Mechanical design of axial flux motor with includes both rotor and a stator (15 KW)
- Project 2: oil cooled radial flux motor
- Converted an existing water cooled ( water jacketing) radial flux motor of power rating 260 KW to an oil cooled (direct injection) and doubled it current rating and total power using ANSYS fluent (CFD)
- Model preparation in Spaceclaim, Meshing and analysis in ANSYS Fluent with different topologies, interpreting results for further design changes
- Project 3: Cold plates for IGBT cooling
- Thermal and mechanical design of different cold plates which are used as heat sinks for IGBTs mounted in
- The motor control units using ANSYS
- Model preparation in Spaceclaim, meshing and analysis in fluent-steady state thermal
- Coupled system
- Project 4: Integration of Electric Vehicle ( gross weight of 65 ton dump truck)
- Examined the functions of each EV subsystem and gained an understanding of the topology of an EV
- Developed the layout for the vehicle level integration with the entire propulsion system while cooperating with the cross-functional teams and taking into account different factors like weight distribution, ideal wiring length, serviceability, etc
- The mounting brackets for each integrated Subsystem were designed by performing structural analysis,
- And optimized in ANSYS
- Topology optimization was used for all the structures using compliance, weight, and stress as constraints
- DFMEA like Shock, Modal analysis is performed for all the mounting brackets for all the traction and
- Power subsystems to avoid failures and unwanted noise
- Determined the primary vibration sources for the motor-gearbox assembly
- To avoid having external vibrations excite the system modes, the appropriate vibration mounts
- Were chosen using modal and harmonic analysis
- Completed detail design and drawings
- Lead the team for the complete integration and testing of the vehicle Multi-objective optimization is used to optimize the motor rotor profile
- Determined the rotor design's current flaws and areas for improvement
- Created manufacturing and geometric constraints in MATLAB and coupled ANSYS Mechanical with it for iterative runs in batch mode
- A multi-objective optimization problem with electric efficiency and performance characteristics as objectives, stress as a constraint, together with manufacturing and geometric limitations, was designed
- The optimization problem is solved using genetic algorithms
- Rigid body dynamics
- Performed rigid body dynamics for various transmission mechanisms like gear trains, propeller shaft to find the allowable miss alignments and complex angles by keeping reaction forces and input-output accelerations as constraints
- Battery thermal management system
- Performed thermal calculations to choose the BTMS's compressors, condensers, heat ex-changers, and other components
- To simulate the system's performance, all components and system interaction are mathematically modeled in Octave
- Simulated driving cycle circumstances are used to gauge real-world performance and establish the temperatures at which BTMS switches on and off
- Successfully tested the unit in the electric vehicle after doing testing and validation on it on a test bed.
