Abstract
Teaming to Achieve a Robust LOTAR Capability for Engineering Analysis & Simulation Data
The
LOTAR International consortium of Aerospace and Defense manufacturers creates and promotes standards for long-term archiving and retrieval, (LOTAR), of digital product and technical data, based on standardized approaches and solutions, mainly relying on ISO 10303 STEP standards. The Engineering Analysis and Simulation Working Group (EAS WG), was created in December 2014.
The initial focus is on quasi-static linear internal loads finite element analysis (FEA) for total vehicles (metallic and composite structures).
The EAS WG is teaming with computer-aided engineering (CAE) software companies to develop and deploy commercial off-the-shelf (COTS) ISO STEP AP209 ed2 “Multi-disciplinary Design and Analysis” translators to enable the preservation of value in FEA while allowing diversity of CAE tools.
A NAFEMS specialist working group, the Simulation Data Management Working Group (SDMWG), has worked to establish best practices for capturing simulation context and pedigree along with the analysis - which is essential to LOTAR. Several EAS WG members belong to the SDMWG.
About the Speaker
Joseph (Joe) Draper, The Boeing Company
Structural Analysis Engineering (Level 4)
Joe Draper is a Structural Analysis Engineer in the Finite Element Analysis Technical Excellence Center (FEATEC). Since joining Boeing Commercial Airplanes (BCA) in 1988 he has worked in aircraft structural analysis mostly in support of vehicle level FEA as part of the “internal loads” organization for many Boeing transport aircraft (cargo, passenger and/or military variants of 747-200/300/400, 757-200/300, 767-200/300/400, 777-200/300, and 787-8/9). He also trained over 400 engineers to use CATIA-FEM and ELFINI in the early 90’s during the 777 airplane development program. From 2004 he has served as Boeing’s engineering focal in support of MSC Software (Nastran, Patran, etc.). In 2014, Joe became engaged in the LOTAR International – Engineering Analysis & Simulation Working Group as the co-leader for the Americas.
Before joining BCA, he worked in Boeing Military Aircraft as part of the internal loads group for the B-2 bomber. Before coming to the Pacific Northwest, Joe worked at E-Systems (MC-130 Combat Talon II, Greenville, TX), Gulfstream (Peregrine 1500 jet, Bethany, OK), Tinker AFB (Value Engineering, Tinker, OK), and Detroit Tool & Engineering (tool & die, special machinery, Lebanon, MO) since receiving his Bachelor of Science in Mechanical Engineering in 1981 from the Missouri University of Science and Technology (Rolla, MO).
