Professional Experience

CAE Design Engineer, TS Tech Americas Inc., Columbus, OH Feb 2015-present

Crashworthiness & safety: Tested designs for FMVSS 201 (roof, pillars head injury in lateral crashes), 202a (Head restraints, back set and height retention), 207 (Seat), 208 (Lap, shoulder, seat belt, whiplash BioRid & Hybrid3 dummy), 210 (Belt anchorages), 213 (Child restraint systems, isofix-latch system & tether), 214 (Side impact), ECE 17 (Cargo luggage barrier retention)

Tested high strength steel material, modeled & calibrated constitutive yielding, hardening, damage & failure behaviour. Characterized stress state and strain rate effect.

Minimized the play (gap) in front seat manual height adjustment lever post assembly, optimized the design & restored the lever turning range. Resolved the unwanted local deformation caused by forces during assembly of plastic cover with the metal lever

Analyzed different countermeasures (design, material & thickness) for bracket to support the designers and testers. Proposed & validated best strength increase, cost reduction, assembly ease & weight-down trade-off. Prevented the pop-up of cup-holder in middle row mid-center seat due to inadequate snaps. The new design steel bracket was added to the back frame as a recall fix.

Managed, coordinated, assigned & outsourced CAD & mesh development projects with offshore designers & contractors

Established and corelated front seat ‘holdability index’ with test and FEA of 50 and 95 percentile 3D HPM1 Oscar dummy

Created and maintained design schedules, performance & regulation compliance, CAE reports as per ISO 9001, standard practices & specifications, and technical presentations.

Saved 93% server storage space for entire team by suggesting, testing & implementing FEMzip software integrated with Compute Manager - a web-based job submission, management & monitoring portal

Established efficient cloud computing utilization guidelines for team by job classification & core/s selection. Created & maintained schedule for annual research items for modeling improvement and accuracy.

•Proposed design, assisted test & validated performance of next-generation head rests to meet G value, energy absorption & pop-out specifications. Products ranged from multi-adjustable front headrests for luxury SUV, rear seat headrests for midsize sedan, second & third row for minivan and finally driver & passenger of 2-door sportscar.

•Performed vertical pull, vertical jig loading, grabstrap pull, lateral helmet lock forces test correlation for sport & cruiser motorcycles at MORP & PORP sit points. Supported similar powersports applications like side-by-sides, ATV's, golf-carts & personal watercrafts.

•Established specification using FEA for recurrence prevention by avoiding pop-out of side-wing under certain bully load condition

•Designed, tested & developed prototype for 'Gap-catcher' & 'Foam-blocker' to avoid dirt & debris accumulation between front seat & center console. Completed benchmark comparison, intellectual property study and applied patents for new ideas.

•Performed durability, life-prediction & reliability analysis using Minitab software for warranty claims and marketability of power rails to prospective customer.

•Helped team achieve weight reduction in seat frame minor model change (5%) and rear armrest (20%). Supported design & test engineers to validate light-weight designs for seat frames. Proposed, modeled & tested new materials including high strength steels, aluminum alloys, plastics, foams, EPP & composite resins to achieve target.

Successfully led and encouraged four company-wide & intra-company CSR activities by serving in the 'Recreation committee'.

Graduate Researcher, University of Cincinnati, Cincinnati, OH Sept 2011-Nov 2014

Implemented & tested generalized incremental stress state dependent damage model for dynamic load tests.
