Design and analysis of mobile equipment for underground mining using Solidworks, FEA, and classical calculation methods.

-Performed calculations used to qualify designs of Class 1 and Class 2 components of nuclear pressure vessels according to ASME Boiler and Pressure Vessel Code.

-Structural analysis using ANSYS finite element software and classical, closed-form solutions formuated with Mathcad software.

-Prepared technical reports.

-Created tooling designs, manufacturing planning, costing and logistics for aerospace gears and transmission components.

-On one project lowered operating costs from over $25,000 to under $10,000

-Liaised with internal and external suppliers to expedite research and development projects.

-Assisted in the assembling and operation of test fixtures simulating main rotary drive transmission systems to be installed in military helicopters.

-Designed components and assemblies for injection molding machines for sale on the global market.

-Developed and designed custom options on original equipment for special needs customers.

-Performed finite element analysis to ensure machine components met stress and deformation constraints and optimized material usage. Prepared written reports from obtained results.

-Acted as team leader on a Continuous Improvement project for the purpose of increasing manufacturability of machined and fabricated components. Procedures implemented from project findings provided initial estimated cost savings of $200,000 per year.
