PROFESSIONAL EXPERIENCE
Vehicle Dynamics Engineer, UTA Racing, FSAE, USA 08/2014 to 08/2016 Designed and manufactured A-arms, sway bars, bell cranks, tie-rods & pull rods by DFMEA, GD & T and FEA. Analyzed and simulated suspension characteristics on MATLAB & CarSim for better ride feel and performance. Track tested cars to read the understeer & oversteer with MoTeC data acquisition to tune dampers and sway bars. Performed regular hands-on work with weight balancing, camber & toe tuning and parts installation.
Steering Lead Engineer, Road Runners, SAE BAJA, India 05/2012 to 02/2014 Designed Ackermann steering geometry for specified race track dimensions and evaluated steering parameters.
Designed and manufactured steering parts with required standard strength and FOS on SolidWorks FEA simulation.
Designed the steering wheel and steering column for universal driver ergonomics on par with roll cage rules.
Performed objective track testing to observe the functioning of the steering system and tune settings.
Intern, Hand-in-Hand India 02/ 2014 to 05/2014 Researched, analyzed & prototyped 3D printed Windrow blade profiles for optimum structural strength & functionality. Produced 40% efficiency in mixture quality from pure mechanical power compared to commercial turners.
Intern, Carnation, India 11/2012 to 12/2012 Analyzed and Applied different types of service & maintenance techniques in engine, sensors and chassis systems. Performed alignments such as toe angle utilizing a four post car alignment lift by adjusting offset angle within range.
Intern, Integral Coach Factory, India 06/2012 to 07/2012 Fabricated railway coach exterior trims by CNC machining, sheet metal forming, punching and shearing. Trained in the working principle of three different braking systems of railway coaches including emergency
braking to assist engineers in improving the brake line tube bending process by redesigning the process flow.
Intern, Ashok Leyland, India 05/2012 to 06/2012
Assisted engineers on Ashok Leyland H-series diesel turbocharged engines for commercial trucks on assembly lines.
Tested and calibrated steering linkages after final assembly on jigs for proper installation and functionality. PROJECTS Design of variable 4-wheel steering of an electric utility vehicle to improve maneuverability spring 2016
Analyzed the geometrical and theoretical steering angle maps of the wheels and defined Ackermann Parameters. Evaluated pneumatic trail data on Optimum T by processing raw tire data of Hoosier 20.5x13x6 tires. Evaluated total torque required at the steering wheel by torque transfer from wheels through the steering linkage. Determined the rack gains and pinion gear dimensions upon iteration for front-to-rear force transmission.
Design of bump steer analysis tool for minimum bump steer by optimally setting tie rod points fall 2015 Generated data table with possible combinations of inboard tie rod points with pickup points as input in MS Excel. The outboard tie rod points are finalized from plotted trends of bump steer angles vs bump and rack displacement
that would produce minimum bump steer through the full range of motion. Improvement of suspension characteristics for Electric car with emphasis on increased laden weight pring 2015
Developed a load transfer spreadsheet to determine new spring rates and ARB rates from standardizing roll gradient. Simulated quarter car control model in Matlab for natural frequency from bode plots and time response curve. Evaluated the yaw rate by performing slalom analysis and compared with that of combustion FSAE cars.
Bearing replacement on a Honda F4i engine with complete overhaul fall 2014 Dismantled and identified the worn out journal bearing and ordered a new one with the right part number. Performed cylinder honing, valve lapping, plastic gauging and feeler gauging according to standards specified in manual.
