Experience:

JNE Consulting Senior Mechanical Engineer 9/08-4/10

. Designed Praxair's Whiting Hydrogen Plant piping using Autopipe to verify

that the layout met ASME B31.3 Code. Also analyzed stress levels and

verified nozzle loading was safe for the vessels (ie. Heat exchangers,

pumps, etc). Designed pipe loops to reduce expansion stresses in the

piping and incorporated spring hanger systems to alleviate high loading

on nozzles. Used Process and Instrumentation Diagrams to correctly apply

thermal loading based on the piping layout, specification, and design

materials. Also used Caesar II for piping analysis and applied

temperature and wind climactic data.

. Specified regulators by determining the heat loading for each building

and making the appropriate calculations to determine the flow rate of

natural gas and the working inlet/outlet pressures.

. Analyzed pressure drops for various line routings using Pipe-Flo, an

incompressible flow based analysis program, as well as Delgas, a Praxair-

based program. Also used Pipe-Flo to analyze the performance of a

centrifugal pump.

Delphi Corporation, Thermal Division Senior Contact Engineer

5/96-7/08

. Worked with OEM customers including GM-North America, GM-Brazil, Opel,

and Toyota to improve Delphi compressor product quality by either

reducing compressor vibration and/or implementing vehicle system NVH-best

practices (longer & softer suction line, eliminating ground-outs, muffler

implementation) at customer-based facilities world-wide.

. Innovatively applied engineering physics to attenuate acoustic waves in a

compressor rear head using a baffle (see Publications).

. Redesigned a shut-off valve to improve NVH characteristics relative to

opening / closing pressures on an Air Board.

. Redesigned a valve-plate for 5CVC-compressors to reduce reed dynamics and

stiffen the retainer to dampen vibrations.

. Analyzed and Designed Line mufflers and internal compressor muffling to

address customer NVH concerns.

. Performed vehicle-level testing using subjective GMUTS ratings and

objective analysis using Aachen Head recordings in Artemis, DAT-

recordings, acceleration and dynamic pressure transducers of R134a

refrigerant pulsations. Also used modal methods to obtain structural

mounting frequencies with an impact hammer.

. Conducted Pre and Post Compressor Validation and Analysis for assessing

new manufacturing site product performance relative to statistical

historical data and/or customer NVH specification standards.

. Used Statistical packages like Minitab for ANOVA and statistical analysis

(Six-sigma) to accurately assess product NVH issues before becoming

warranty issues. Also used statistical methods for clue-generation so as

to develop DOE experimental approaches to solve engineering problems.

. Documented noise and vibration issues using software like MATLAB,

LABVIEW, LMS Test.Lab, HP3566A, and Artemis for customer presentations.

. Assisted with technical writing for QS9000 and ISO standards and answered

technical questions to help Delphi achieve industrial certification.

AFPS, Inc. Project Engineer 6/93-5/96

Delegated work assignments in Mounting Force area and managed four people.

Programmed graphical user-interface MATLAB routines to analyze frequency-

domain data for strain gages, dynamic force transducers, and accelerometers

with order cut capabilities, waterfalls, and overall frequencies.

Purchased equipment.

Developed a free body diagram of a force transducer array to calculate

total force in a six D.O.F. system.

Praxair Student Intern Spring and fall 1992

Redesigned a manual force transducer into an automatic pneumatic system.

Carrier Transicold Corporation Test Engineering Technician 6/92-

8/92

Located resonant frequencies with a shaker table to determine refrigeration

unit durability to vibration inputs.
