Experience:

Assistant Professor Sept 2013 – Dec 2014

Department of Mechanical Engineering, Avanthi Institute of Engineering and technology, India

• Offered the subjects of Engineering Mechanics, Thermodynamics and Kinematics of Machinery for Undergraduate students. Conducted exams and evaluated the performance of students and assist them.

• Conducted the lab ‘Thermodynamics’. Worked with department heads on various academic projects. Recommended students for participation in course-related research projects. Academic Projects:

Active Yaw Control of a Vehicle with AFS and DYC using a Fuzzy Logic Algorithm Jan 2018 – April 2018

• Developed 7 DOF vehicle model from model based equations in MATLAB/Simulink with non-linear Dugoff tire model

• Vehicle responses in standard NHTSA tests Fish-hook maneuver, Double lane change are observed to validate model

• Developed Active front steering(AFS) and Direct yaw moment(DYC) controllers using Fuzzy logic, added to the 7 DOF vehicle model to control vehicle yaw rate response

• Additionally, Sine wave and trapezoid steer inputs with and without external disturbing moment are given as inputs and the controlled vehicle showed improvement in vehicle handling and stability

• Additionally, added a simple ABS logic to control the wheel slip for maintaining AFS functions when ESC is acting Active steering control of vehicle model using PID controller Jan 2018 – April 2018

• Modelled a Bicycle model in MATLAB and Simulink using transfer functions and a PID controller is added

• Analyzed response by giving a step steer input. Tuned PID controller using Zeigler Nichols method. Improved response by decreasing the overshoot of steer response to 1.7% and settling time to 0.1526 Vehicle stability and control systems Jan 2018 – April 2018

• Modelled a nonlinear Dugoff tire model in MATLAB and analyzed slip angles and cornering forces in different maneuvers such as braking, braking and steering under different friction conditions

• Calculated the stability equations for Trailer, Bicycle model, Quarter car model, Full car model, Four-wheel steering, Four-wheel driving, etc

Semi-Active suspension response over a speed bump Sept 2017 – Dec 2017

• Developed a simulation model of quarter car in 20-sim 4.6 using Bond graphs for response over a speed bump

• Semi-Active suspension algorithm modifies the damping coefficient of shock absorbers at runtime dynamically. This would reduce the transmissibility of the setup, resulting in an improved ride quality during body roll as well as bump Adaptive Cruise control using PID controller Jan 2017 – April 2017

• A Simulink model for demonstrating the adaptive cruise control system to control distance and speed was modelled

• PID controllers, one for safe distance & one for set speed control along with host car and lead car are used in the model Benchmarking, vehicle specification and pugh analysis Sept 2017 – Dec 2017

• Vehicle specifications target for proposing a MY 2023 mid-size pickup truck segment, considering Nissan Frontier as reference vehicle, are obtained using the benchmarking & Pugh chart tools for consumer needs, vehicle systems, etc QFD, Cascading requirements and Interface analysis Sept 2017 – Dec 2017

• Functional specifications for instrument panel sub system of the vehicle are obtained using a QFD from customer voice

• Cascaded the requirements from a vehicle level to systems, subsystems and component level. Developed an Interface matrix between different vehicle systems through interface analysis Business plan development Sept 2017 – Dec 2017

• Developed a business plan for a MY 2023 automobile involving the operational costs, engineering and design costs, facilities and development costs and other costs considered at present value

• Developed Gantt charts, cost and revenue tables, V model. The business plan considered 2 facelifts after initial vehicle introduction

Technology plan Sept 2017 – Dec 2017

• Conceptual Design of Vehicle for a 2023 MY automobile including the side view and plan view of the vehicle and Technology plan discussing technological changes planned, challenges and open issues, risks and counter measures Material selection Sept 2016 – Dec 2016

• Alternate material selected for an accelerator pedal and arm using the Ashby’s material selection charts and the analytical min-max method and the method of weighing factors with Cost, Mass, Corrosion Resistance, Manufacturability, Recyclability, Sum as factors to choose a material Internships:

• VISAKHA CONTAINER TERMINAL, Visakhapatnam, India Sept 2012 - Mar 2013 MAINTENANCE OF HYDRAULICS USED IN PORT EQUIPMENTS. Was assigned for maintenance of hydraulic machines used for transferring the containers by following the ‘Preventive maintenance method’.

• VISAKHAPATNAM STEEL PLANT, Visakhapatnam, India Nov 2011 - Mar 2012 THE STUDY ON LUBRICATION SYSTEM IN WDS6 LOCOMOTIVE. Analyzed the lubrication system for a WDS6 Loco engine and checked for lag in lubrication system flow. A pipe is redesigned for improving flow.
