Associate Researcher (Noise and Vibration)

Worked with the team of NVH researchers with the goal of reducing noise and

vibration of the gasoline DI systems and its components in the vehicles. My

role included the following responsibilities and tasks:

< Plan, formulate, and schedule the tests for noise and vibration

measurements. Prepare fixtures, test setup and instrumentation required

for the experiment. Work with technician to run the test cell.

< Acquire acoustic and vibration signature levels for SIDI system using

LMS SCADAS III (Front End) and LMS Test lab (Processing software) in an

anechoic chamber.

< Testing of different acoustic insulation, absorption and damping

isolation materials to optimize the material combination to control

noise and vibration.

< Conduct vehicle engine/transmission vibration and noise measurements to

study airborne/structure borne noise characterstics to the cabin.

< Support NVH activities to the suspension system (shock absorber) for

ride comfort and handling evaluation utilizing 4-post shaker machine.

< Troubleshoot the noise problems using test methods like modal analysis

and sound intensity mapping.

< Data interpretation and detailed analysis of results in time and

frequency domain to enable root cause analysis and develop

countermeasures for NVH improvement.

< Computational analyses include structural, harmonic response, modal and

sound radiation analysis using ANSYS [FEM] and LMS Virtual Lab

(Sysnoise) [BEM] respectively to validate experimental methods. Used

SolidWorks as 3D CAD software to modify the design according to results

and iterate the analysis.

< Benchmarking the current products and evaluating the new generation

designs.

< Interfacing with customers, design and release engineers to discuss

test results, future NVH targets and road map to reach the targets.

< Travel/visit to the customer site to conduct component/vehicle

measurements.

< Prepare the technical reports and presentations to the internal and

external customers.

Research Assistant (Clemson University- BMW Manufacturing, USA)

Thesis: Research and Development of non-contact optical precise gap

measurement system for quality control of interior vehicular trim

components and enable root cause analysis. Funded by BMW Manufacturing,

USA.

Led the project from the concept to prototype and the final optimized

functional model.

< Used Quality Function Deployment (QFD) to covert customer voice into

technical specifications.

< Developed functional structure, concept and designed hand held gap

device. SolidWorks is used for CAD modeling. A prototype is generated

for further evaluation of the product.
