Senior Structural Engineer

Eight-year experience improving mechanical design through mathematical

modeling, numerical simulation, and test correlation in defense and heavy

construction equipment companies.

Saved millions of dollars by reducing prototyping phases in new product

development, reduced warranty payouts by extending product life, and

exceeded customer's specification by delivering quality work ahead of

schedule for immediate design review.

Skills include finite element modeling, stress/thermal/fatigue analysis,

test correlation, and multi-body system dynamic simulation.

PROFESSIONAL EXPERIENCE

BAE Systems Land & Armaments LP, Santa Clara, California 2005- 2009

Sr. Staff Analysis Engineer (2007- 2009)

. Improved performance and durability prior to production of U.S. Army's

Future Combat System (FCS) Manned Ground Vehicle (MGV) by developing

virtual prototyping of vehicle system through Integrated System Model

(ISM) in Matlab/Simulink and DADS/VL Motion.

. Reduced 66% simulation time by streamlining ISM simulation process for

FCS MGV in Matlab/Simulink.

. Exceeded customer's specification for immediate design review and field

test by delivering the ISM towing simulation result ahead of schedule for

future recovery maintenance vehicle.

. Eliminated fatigue and fracture failure in the structure and component

design of Joint Light Tactical Vehicle (JLTV) by performing detailed

stress analysis in I-DEAS and NASTRAN.

. Led a ten-person team to perform FCS project on schedule and control

expenses within budget by effectively establishing monthly milestone

schedules for detailed tasks.

Analysis Engineer (2005-2007)

. Reduced cost for design review of FCS MGV by delivering mobility load

data to structural analysts without performing field test through rigid

body dynamic simulation in DADS under various scenarios.

. Established the standard design duty cycle for FCS MGV by developing

mission profile for vehicle structural and propulsion systems.

. Identified uncomfortable ride quality design criterion for FCS MGV

established in NATO Reference Mobility Model by implementing ISO2631-1

(mechanical vibration and shock-evaluation of human exposure to whole-

body vibration) for crew comfort analysis in Matlab.

. Optimized mobility performance of FCS MGV rubber band track by developing

hyperelastic material model through test correlation in ABAQUS.

. Reduced process time by 33% in the real time simulator of FCS MGV

integrated system by developing a neural network model for vehicle

propulsion system in Matlab and Simulink.

Caterpillar, Inc., Champaign, Illinois 2001-2005

Senior Engineer (2004-2005)

. Achieved 91% benchmark test correlation with simulation data by

validating developed system structural model of next generation motor

grader in DYNASTY through on-vehicle-stress-analysis.

. Saved millions of dollars in reduction of prototypes for next generation

motor grader design improvement by developing virtual product development

simulation in DYNASTY system structural model through Six Sigma process.

. Reduced need for warranty payouts of large wheel loader by improving the

product durability through virtual proving ground simulation in DYNASTY

system structural model developed and validated through on-vehicle-stress-

analysis test correlation.

. Controlled expenses within budget by creating monthly labor hour report

for all company site projects.

Senior Project Engineer (2001-2004)

. Saved budget for design iteration of off-highway truck droptube due to

fatigue failure by implementing detailed stress analysis on casting re-

design in NASTRAN and FE-SAFE.

. Validated proposed final design of off-highway truck droptube to design

team prior to production by performing OVSA test correlation in DATK and

DYNASTY.

. Prevented fatigue and fracture failure in mechanical and engine

components by performing detailed structural and thermal stress analyses

through the dynamic load from system structural model in I-DEAS and

NASTRAN inertia relief.

. Improved work quality and increased productivity by providing NASTRAN on-

site technical support and training.

University of Illinois at Urbana-Champaign, Illinois

2000-2001

Post-Doctoral Research Assistant

. Led the research project of "Application of Neural Networks to the

Inspection of Railroad Rail", funded by Sperry Rail Service.

. Developed the first Neural Network software in FORTRAN detecting faults

in rails through ultrasonic waves in real time inspection in U.S.

. Presented technical paper at the 25th Quantitative Nondestructive

Evaluation Conference.
