Ashish Kumar Sahu received his B.E. in mechanical engineering in 2006 from the Bhilai Institute of Technology, India, and his M.Tech. in mechanical system dynamics and controls in 2008 from the Indian Institute of Technology, India. He gained two and a half years of experience in durability testing at Tata Motors, followed by nine years in structural analysis at Mahindra and Mahindra. His expertise lies in finite element analysis for stress and vibration. In September 2020, Ashish joined the McMaster Automotive Resource Center (MARC) at McMaster University, Ontario, as a Ph.D. student. His research focuses on the acoustic vibration of switched reluctance motors.
Full Profile
Following graduation, Ashish joined Tata Motors as a graduate trainee. He worked on vibrational fatigue and structural durability of automotive components. He gained hands-on experience with various fatigue testing instruments and methodologies. Ashish developed lab tests using servo-hydraulic actuators and vibration shaker tables. This expertise helped him build fatigue test rigs to evaluate suspensions and axle beams of commercial vehicles.
After two and a half years, Ashish moved upstream in design and development by joining Mahindra and Mahindra as a vehicle durability analyst. This role gave him more freedom to design components in the initial stages of development. He was responsible for structural durability of the body in white, chassis, axle, suspension, and interior and exterior trims. He contributed to two full-scale and multiple facelift projects. Ashish improved simulation results by correlating them with static and dynamic physical test data. He also demonstrated simulation capability for composite automotive body structures. Additionally, he developed procedures for multi-disciplinary optimization of automotive body structures. His nine years as a simulation engineer resulted in six SAE technical publications.
With the rise of electric and hybrid vehicles, Ashish became interested in new challenges related to EV drivetrains. He is focusing on acoustic noise and vibration in electric motors, a significant issue in electric drivetrains. He is currently pursuing his Ph.D. under Dr. Ali Emadi at MARC. Ashish also works as a research assistant with Stellantis Inc., evaluating the structural integrity of permanent magnet synchronous motors (PMSM).
