Cummins
Stress Group, Midrange Engineering, Cummins Inc Senior Structural Analyst
Mar ’10 - Present  Responsible for lubrication & cooling components, and cylinder block validation for 2013 B and L engine families, and current product support for all B, C and L engine families  Analytical Work o Performed FE analyses using ANSYS Classic & Workbench 12.1; modal analyses, structural analyses subject to non-linear material properties, contacts, large displacements, and gaskets o Developed calibrated FE models to predict / understand on-engine failures, and formulate solutions using analysis-led-design methods o Developed 1-D hot bolted joints tool to predict load loss of exhaust manifold capscrews at elevated temperatures o Guided analysts in off-shore location (Cummins Research and Technology India)  Experimental Work o Performed on-engine strain & acceleration based validation of engine components (Frequently used tools: Waterfall plots, FFTs, Overall Levels, digital filters, Modified Goodman Plots, Reliability calculations etc.). Used FE results to decide strain gage and accelerometer locations. o Conducted ultrasonic bolted load testing, using MicroControl MC900 transient recorder, MC911 software to quantify cold relaxations, thermal relaxations, assembly loads etc. o Quantified gasket sealing pressure distributions using pressure sensitive paper (Prescale Fujifilm paper) o Determined fatigue properties using resonant dwell and staircase fatigue methods on shakers o Measured friction coefficients and strengths for bolts using Torque-Tension & MTS machines  Capability Development o Developed Functional Excellence Processes for analytical & experimental validation of turbocharger oil drain tubes o Developed processes for standardization of analysis and documentation of oil & coolant lines, to drive efficiency, consistency and quality o Responsible for identification of opportunities for process and capability improvement, and execution of projects to drive continuous improvement o Led turbocharger stud capability; which resulted in quantification of cold joint measurement error across facilities, and determination of high temperature material properties Midrange Customer Engineering, Cummins Inc Current Product Validation Engineer
Jan ’08 – Mar ’10  Managed multiple engineering projects each dealing with reducing high warranty costs on Customer Engineering component/subsystem  Lead geographically diverse teams of designers, analysts, service & quality engineers, personnel at distribution centers & manufacturing plants, as well as external suppliers & contractors, to solve major product problems  Utilized Fault Tree Analysis method to identify potential root causes of component failure, carried out numerical analysis (FE analysis, Dimensional Variational Analysis), design of experiments, reviewed metallurgical reports, metrological reports, supplier capability reports, conducted in-field testing etc to narrow down and identify key root causes to product failure  Chaired meetings with Korean & Japanese counterparts; Was responsible for Hyundai Heavy Industries’ engineering account for warrantable failures
