Work History
Brake NVH Engineer
MOBIS Technical Center North America
11.2021 - Current
- Support and led the NVH development for Stellantis KM49 BR2, KM74 BRY, EJ BR2-BR3, LB BR2, WL BR1-BR2 programs
- Determined, evaluated and successfully implemented NV solutions when faced with results which don't meet customer or internal NV performance targets
- Acquired thorough knowledge on NVH countermeasures including rotor material & geometry changes, caliper modifications, and brake pad modifications & insulators
- Resolved vehicle cold room noise issues with countermeasure developed through shim & pad shapes on multiple programs
- Supported customer request by preemptively coordinating, and completing CAE analysis for low frequency concern to modify caliper designs before TKO
- Act as a key NV interface between the OE customer, Tier 1/2/3 suppliers, HQ test department and local project teams
- Led in coordinating NV Testing and CAE- brake squeal analysis
- Ensure NV targets are met through on-time test completion
- Prepared and presented NV related test reports and presentations internally, and to the customers
- Hands-on experience in FRF measurement of brake rotor, caliper housing, bracket & pads using Siemens test lab
Brake NVH Engineer
Ford Motor Company
05.2019 - 11.2021
- Managed, and led the NVH Development for the S650 Mustang program, 17-, 18- and 19-inch front and rear brakes
- Assessed and met the brake NVH health chart items in line with program milestones and deadlines
- Prepared and presented the NVH development progress to the program team on a weekly basis
- Developed counter measures for in-plane rotor modes working with CAE engineer, friction and shim supplier thereby eliminating the cost to tool new rotor design
- Reviewed and analyzed CAE component and system level data, with dyno test data developing countermeasures for various squeal noise frequencies on front and rear system
- Evaluated brake NVH performance on corner dyno’s, chassis dyno and vehicle
- Led the chassis dyno brake squeal LACT & cold room procedure development to improve Brakes DV efficiency in saving cost and time
- Completed correlation tests on the chassis rolls with different vehicles assessing the noise level and creating a sign-off procedure
- Ran chassis dyno shakedown BEV squeal procedure, analyzed and recommended further improvements for developing sign off procedure on the regen brake system
Brake Test Engineer
Brake Parts Inc, Research & Development
07.2017 - 04.2019
- Scheduled, prioritized, and ran inertia dynamometer tests on multiple vehicle platforms
- Spearheaded and conducted NVH & FMVSS 135 testing with different types of paint. Validated test results and showed reduction in noise level, increase in performance with the paint meeting customer requirements & deadline
- Developed a new rotor crack test procedure and devised a test plan to benchmark BPI fleet rotors with OE rotor
- Supported sales & marketing team by benchmarking BPI rotors & material with competitors inside the salt spray testing (ASTM B117) for over 400 hours. Developed corrosion burnish procedure and analyzed the test results to reflect changes in brake effectiveness
- Coordinated with product development team and performed a study on friction material with & without underlayer tested inside the corrosion chamber for over 500 hours. Performed shear testing and proved material with underlayer prevented reduction in shear strength after corrosion meeting customer requirements
- Familiar with federal standards (FMVSS 135 & 105), SAE J2707, SAE J2521, SAE J2522, SAEJ661A, JASO C427, Link USCT, Pomona, ISO26867, ISO 6310 method B and GB 5763
- Devised a test plan to benchmark BPI rotor & police fleet material with competitors by running Pomona/EVOC procedure. Analyzed the test results and proved BPI rotor & material are as good as competitor in terms of wear, performance
- Reduced time and cost by implementing the idea of using muriatic acid with water to remove coating from rotor surface. Recommended and ran ISO 26867 to evaluate performance of different type of BPI police rotors with fleet friction material
- Responsible for purchase of accessories, maintenance and repair of dynos, chase, compressibility, GB tester and corrosion machine
