Project Work Experience

Simulation and Analysis of Up Shift Process in a 6-speed Automatic Transmission. 02/2017-03/2017

• Established a mathematic model for the transmission-vehicle system consisting of general state variable equation, specific state variable equation for the 1st gear, 1-2 shift process and 2nd gear operation.

• Simulated the launch of the vehicle from rest in 1st gear, initiated 1-2 shift at a speed of 15 mph, and 2nd gear operation for 2 seconds with an open torque converter and a fixed throttle position using MATLAB/Simulink.

• Reduced torque overshoot by spark retarding, and careful calibration of the oncoming clutch. Further, torque hole was reduced to maximum extent with help of spark retard. Modeling of Vehicle cooling system. 11/2016

• Built a Simulink model of vehicle cooling system consisting of four sub models namely, engine operation, air flowrate, coolant flowrate and heat transfer.

• Determined coolant flow rate, heat rejection from the engine, and engine outlet coolant temperature for different vehicle speeds by executing the simulation model.

Computational Analysis of Hemispherical Radiating Fin. 01/2015-04/2015

• Derived heat transfer equations by using two-dimensional conduction equation in spherical coordinates and subjected the same to radiative boundary condition, with constant base temperature. Solved derived equations using Finite Difference Method and Gauss-Seidel iterations by writing a code in FORTRAN 95.

• Determined Heat transfer improvement as a function of thermal conductivity and emissivity, with and without irradiation. The hemispherical fin starts to radiate heat for thermal conductivity > 3 (W/mK) and absorbs heat for thermal conductivity < 3 (W/mK).

Vehicle Integration - Conceptual Design of 2021 Toyota Highlander. 09/2016-12/2016

• Collected Customer requirements from surveys, websites, magazine and, blogs.

• Conducted a benchmarking study of competitor vehicles with the reference selected vehicle.

• Developed Pugh Diagrams to compare the reference vehicle with the target vehicle and benchmarked vehicles.

• Determined target specifications through the application of the Quality Function Deployment (QFD) to a selected vehicle system (Instrument panel).

• Developed interface diagram and matrix for the selected vehicle system included all major sub-systems.

• Incorporated System Engineering ‘V’ model to show timings and various gateways in the vehicle program.

• Determined costs and conducted financial analysis for the vehicle program.
