Fiat Chrysler Automobiles US LLS – RGBSI Auburn Hills, MI Design and Release Engineer Jan’17 - Present

RAM 2500/3500 (Heavy Duty Trucks) & RAM 1500 (Light Duty Trucks)

• Responsible for release of design for Heavy Duty Rear Axle assemblies of RAM Trucks. Major components included “Adjuster Nut”, “Drain Plug Magnet”. Achieved differential carrier rejections by 5%.

• Analysed performance of Limited Slip Differential – Clutch Type. Suggested changes which resulted in weight reduction by 3lbs & hence reduced axle vibrations.

• Validated the changes in design of the Axles at Design and Production stages. Documented the proposed changes in Change Notice and Common Change Document.

• Developed & Simulated the test procedures to test and validate the performance of the axles on proving grounds at different schedules and tracks.

• Checked the safety critical requirements (Spill Prevention) and verify them being met by the supplier.

• Coordination with various internal cross functional teams (Design, CAE analysis, Testing, Data Acquisition, Chassis team, Suppliers and Axle Assembly) and external Suppliers for operational consistency.

• Worked with CAE team to perform Virtual analysis (Stress, Fatigue, NVH, and CFD) to validate design analytically.

• Controlled contamination of the lubrication by 50% by generating specifications for level of contamination in Axle assembly.

• Implementing GD&T, Best Standards, Benchmarking, Stack-up analysis, plan, and develop documents: DFMEA, DVP&R, and Best Practices.

• Working on DFSS project for Differential Lubrication Optimization. Kettering University Flint, MI

Research Assistant – College of Engineering Oct’15 – Dec’16 Modelling and Simulation - Axial Piston Pump

• Developed Simulink Model to simulate the working of an Axial Piston Pump using Model-Based approach and used Amesim to replicate the results.

• Analysed the data from the Simulink model to calibrate the hydraulic pump model and Reduce Noise by 40% for best Swashplate moment based on the results.

• Develop an alternate Power Control Mechanism, using Matlab/Simulink to vary the performance, efficiency and flow of the Pump.

• Proposed the findings in the publication at 11th IFK (International Fluid Power Conference), Aachen. Simulation of a Hydraulic Crane System using a Counterbalance Valve using Bond Graph

• Successfully predicted the Dynamic Response of a Hydraulic system using Simulink, S-Functions.

• Utilize Matlab and Simulink tools to develop power control models and used Amesim to validate the model.

• Diagnosing and troubleshooting the control related issues to replicate the working of a counterbalance valve. Counterbalance valve used to prevent the running away of the load in neutral.

• Developed the Mathematical Model of the Crane System using the Power Bond Graph technique. The technique can be employed to develop multi-disciplinary system models and study the interaction of various components.

• Proposed the findings in the publication at 11th IFK (International Fluid Power Conference), Aachen. Education:
