Automotive Engineering graduate from University of Michigan with 2 years’ extensive experience in Research and Development at a leading OEM. Seeking full-time opportunities in the field of Design and analysis. EDUCATION

Master of Engineering in Automotive Engineering, Sep. ’16-Dec.’17 University of Michigan Ann Arbor, USA GPA: 4.0/4.0 Bachelor of Technology in Mechanical Engineering, July. ‘10 – June.’14 University of Kerala, Trivandrum, India GPA: 4.0/4.0 SKILLS

Unigraphics Siemens NX9 GD&T KISSsoft HyperMesh LS Dyna OptiStruct Matlab DFSS Teamcenter Siemens PLM DFMEA Tolerance Stack-up CATIA V5 ABAQUS DFM Minitab C++ PROFESSIONAL EXPERIENCE

Assistant Manager-R&D Transmission Design, Mahindra & Mahindra Ltd. India Aug. ’14-July.’16 Implementation of 4-Wheel Drive in 50HP Tractor Model:

Carried out 3-D assembly and 2-D drafting as per layout in Unigraphics NX9 to implement 4-WD in the base model.

Conducted design and analysis of critical components like dropbox, gearbox housing etc. jointly with CAE team.

Selected gear ratios based on slip calculations & designed gears using KISSsoft.

Carried out tolerance stack-up of components within the dropbox assembly.

Led the prototype assembly team for the transmission assembly for new product development. Value Analysis/Value Engineering (VAVE) Projects:

Design optimization for differential cage assembly, clutch actuation shaft, rear axle and layshaft using NX9.

Modified gearbox housing cross section and ribbing pattern for reduced material usage without sacrificing strength.

Overall production cost reduced by 9% per tractor. Resolution of Field Failure of 11" Dual Clutch:

Determined failure reason to be clutch slip caused by reduced clamp load resulting from higher loading conditions.

Proposed & implemented an increased clamp load spring Design, based on Factor of Safety & energy calculations.

Was awarded Mahindra Yellow belt for resolving the issue. Gear Noise Reduction in 1st Reverse Pair of 24HP Tractor:

Performed contact analysis in KISSsoft on the gear pair.

Proposed a new design with reduced peak to peak transmission error & improved the contact ratio to reduce gear noise. Root Cause Analysis of Input Shaft Cylindrical Roller Bearing Failure:

Root cause for failure determined by performing shaft deflection calculations in KISSsoft.

Higher deflection value obtained due the proximity of roller bearing with the input shaft gear.

Improved bearing design by providing crowning along lead of the rollers to take up higher deflection. Software Integrity Intern-Altair Engineering Inc. Troy MI May ’17-Aug’17

Assisted the software integrity team in testing and evaluation of various functionalities of Altair products- HyperMesh & HyperView in both Windows & Linux OS.

Set up and ran OptiStruct simulations including topology, topography, combination, size and shape optimizations and developed automation scripts for the same.

Developed automation script in Tcl, evaluated automation reports and validated fixes to bugs reported. Research Assistant-University of Michigan Transportation Research Institute (UMTRI) Sep. ’16-Present Determine feasibility of 5-point seatbelt with embedded airbag for military application:

Carried out dummy positioning with military gear, seat belt fitting using pre-simulations and mesh morphing techniques, pre-processing using HyperMesh and ran simulations using LS Dyna solver for vehicle frontal collision.

Based on the comparison of kinematics between the test and the simulation plotted in HyperView, as well as acceleration, deflection and force curve comparison plotted in HyperGraph, the seatbelt model was modified for better fidelity.

Modified the belt design parameters for minimum injury and best performance. Improving Parametric Pediatric Head Finite Element Model:

Simulated cadaver tests in LS Dyna using a finite element head model and recorded model-predicted stress responses.

Related responses with fracture test results to optimize the model for better prediction using both linear and non-linear material modeling and develop a baseline for vehicle crash simulations. ENGINEERING PROJECT EXPERIENCE

Determining Stress Concentration Factor (SCF) in ABAQUS:

Modeled weld structures subjected to torsional and bending loads in ABAQUS for varying mesh size.

SCF at critical locations was determined using Tractional Structural Stress calculated from nodal forces, to establish the mesh insensitivity of the method employed.

Body-Structure Design Project:

Applied first order model principles to size a body structure for a specific vehicle package and customer segment.

Translated the requirements for design for crashworthiness, bending and torsional strength and stiffness from the system level to structural elements.
