  Jun 2021 - Aug 2021

  3rd Year Summer Internship:• Worked on computational Finite Elements Analysis - (FEA) of Static, Fatigue (Dynamic Loading) analysis of an impeller used in jet engine applications made up of the lightest additive manufacturing material ‘AlSi10Mg’ using a few possible designs (Notably Lattice Structure).• The Objective was to deduce the lightest effective design through a structural analysis by juxtaposing the critical results obtained via ANSYS 2021(Static Structural) software. Ascertained the threshold boundary conditions for safe operation using the ANSYS Optimization toolbox.• Extended the work to frequency domain dynamic analysis (Modal Analysis) and extracted the significant frequencies and mode shapes of the designs using participation factor and effective mass factor concept.# Guide: Dr. R. Jayaganthan, Professor, Department of Engineering Design, IIT Madras Show less Summer Research Fellowship Programme (SRFP 2021):• Worked on the problem statement of ”Closed-loop identification and control using first order plus timedelay model framework”.• Developed a generalized closed-loop circuit that identifies the system/plant using recursive least squares algorithm (RLS) and designed a Model predictive controller (MPC) for the system with the help of SIMULINK and MATLAB.• Finally iterated and simulated the closed loop under numerous systems to observe the effectiveness of the simulated closed loop.# Guide: Dr. CS Shankar Ram, Professor, Department of Engineering Design, IIT Madras Show less

  Undergraduate Researcher

  Undergraduate Final Year Project: • Designed a wheelchair-to-bed transfer device for paraplegia patients and old age people, that can be operated by the user without external assistance. • Used Solidworks & Siemens NX to design the device assembly, subsuming tactical interconnection of 30 parts over various mechanisms. Ran Structural and Fatigue analysis using ANSYS for checking the performance under operating conditions.• Further, secured a Centre for Entrepreneurship Development and Incubation CEDI - (NIT Trichy) Grant of 1500$, sponsored by Siemens Center of Excellence (COE - NIT Trichy) to fabricate the physical prototype of our Design.* Best Project Award: https://www.nitt.edu/home/academics/departments/prod/projects/studproj/a2022/# Guide: Dr.-Ing.
