ACADEMIC PROJECTS

Vehicle roof-crush safety and strength improvement analysis (FMVSS 216), April-May2016

Designed composite reinforcement along the A-pillar and B-pillar to strengthen the roof rails to resist the crush load during quasi-static loading and analyzed the occupant head clearance after crush

Determined the roof load capability, interpreted the crash data and video data to compare base model with improved model, Achieved 14.8% strength improvement with mass addition of 500 grams [HM & Ls-dyna]

Structural dynamics of a vehicle during Side crash (FMVSS 214), March–April 2016

Modified the side structure with boron steel reinforcement to mitigate the B-pillar and rocker intrusion during side pole crash and deformable barrier crash, [Hypermesh & Ls-dyna]

Side crush force endurance improved by 33% and B-Plr intrusion reduced by 16%

Frontal dynamic impact and crash analysis (FMVSS 208), [Hyperworks & Ls-dyna] January-March 2016

Interpreted results for reasonable conclusion when vehicle structure impacted to rigid barrier

Optimized the frontal rails with composite fiber materials and crash initiators to absorb more energy through progressive folding of the rails.

Studied occupant injury criteria for both unbelted and belted conditions during impact

FEA of automotive component and fatigue life calculation of a flip chip package April-May 2015

Developed FEA model for bracket and piston head geometry in-order to study the stress propagation and interpret analysis results for design recommendation

Determined the fatigue life, stress and deflection of flip chip package subjected to thermal loading and concluded that the life span decreases with impurities and voids in the under fill, [Hyperworks, Abaqus]

Vibration suppression of helicopter rotor blades, [Publication] November 2013-February 2014

Using Matlab codes the FEA model of the helicopter rotor blades are generated to suppress transverse vibration using pendulum absorbers, (International journal of Structural Engineering, Inderscience Publishers)

Through parametric analysis found placing pendulum at the tip of the blade with 6kg of mass being efficient

PROFESSIONAL ENGINEERING EXPERIENCE

Research Assistant, Wayne State Nanofabrication Laboratory, Detroit, MI, USA January 2015 - Present

Research on packaging materials for high temperature (upto 120 ºC) Li-ion millimeter-batteries (<3mm)

Investigated new strategies to improve performance for customer specification by prototyping new designs for millimeter-battery (<3mm) to utilize maximum surface area using UG NX

Performed various testing procedures (capacity, cycle life tests, etc) and documented the results

Ecocar3 Mechanical team member, Wayne State University, Detroit, MI, USA October 2014-December 2015

(GM & DOE sponsored Hybrid vehicle competition for University students)

Packaged complete vehicle architecture for space claim analysis (UG NX) and battery packaging analysis to determine cargo capacity as per SAE standard

Project Engineer, Wipro Technologies, Pune, Maharashtra, India December 2012-October 2013

Responsible for ensuring customer satisfaction with emphasis on quality and timing within the company and outside the company to create jobs based on their requirement and scheduling for global deployment

Proactively performed initial troubleshoot methods on the event of job failure to resolve them

RELEVANT COURSES

Fundamentals of Electric drive vehicle engineering, Fundamentals of Battery technology, Finite element methods-1, and Manufacturing processing mechanics, Modeling and control of Dynamic system, Dynamics-II, Crashworthiness
