More to Know of COE: Boeing Company’s Lee Kruger Talks SIMULIA, Future of Engineering Design

With more years of collective industry experience than can be counted, COE is the place for users of all Dassault Systèmes solutions to share experiences, continue learning and influence the future of Dassault Systèmes solutions. This month we spoke with Lee Krueger, Associate Technical Fellow with the Boeing Company, who talks about his work with SIMULIA, the progress he has witnessed during his 30 years in the field and the exciting future that lies ahead for engineering design.

Please tell us a little bit about yourself.

I am considered a kinematics/multibody simulation and mechanisms design expert, and the only member of the Technical Fellowship to share a name with a high-lift device. I’ve been with the Boeing company for nearly 30 years and have been on the forefront in providing analysis and simulation solutions for the engineering community for over 25 years. I’ve taught classes in FEM/FEA and Multibody Simulation and supported the 787, 747-8, 777, 737Max, 767 Tanker, 777X, PD Studies, Future Combat Systems, International Space Station and legacy airplane programs.

I pride myself with multiple skills, stemming from my broad background of Boeing experience. I hold bachelor's degrees in Aeronautics and Mechanical Engineering from the University of California at Davis and a master's degree in Aircraft Structures from the University of Washington.

Life at Boeing began in 1989, when I was hired directly from college to work in the Air Vehicle Technology Group, providing stress support for engineering drawing release of primary/secondary aircraft structure parts and assemblies (AWACS, Navy E6, Military 707 Derivatives). I have also provided liaison engineering support to address rejection tag concerns for strength check and durability analysis.

I currently serve as the domain manager of the COE Engineering Analysis and Simulation (EAS) group, where I lead and oversee efforts in key areas of analysis and simulation, including FEA/FEM, Optimization, MultiBody Simulation, Model Based Systems Engineering and Virtual Reality.

How long have you been working with Dassault Systèmes products?

I have been using DS products for over 25 years now, and started out using CATIA V3. I have worked with vendor companies to partner with DS for analysis and simulation applications, long before DS owned many of the analysis and simulation tools that are in use today, which includes SIMULIA’s ABAQUS.

Specifically, how are you using SIMULIA, and how have you seen it improve your work?

The use of ABAQUS has proved to be very valuable in our work at Boeing. The ability to predict and analyze the true physics of a product are of great importance to us — not only to prove out a design, but also validate tests. We have also used it in post-production issues and even airline accidents.

Additionally, we have utilized CAA V5 partner analysis tools for analysis and simulation, for acoustics and multibody dynamics. These tools have contributed to the success of the 787, 737 Max, 767 Tanker and Product Development (PD) studies on new airplanes. The ability to utilize parametric design geometry directly in our analyses has proved invaluable in meeting schedules, addressing issues and communicating directly with the design engineers. Our flaps, landing gear, overhead storage bins, flight controls, etc., have all been analyzed within V5 eco-system. We are hoping to replicate the same successes within 3DEXPERIENCE®

Tell us about a recent project you’ve been working on with SIMULIA.

Currently, we are evaluating the merits of Simpack, 3DEXPERIENCE® Kinematics and Dymola within the context of the 3DEXPERIENCE® platform. As we enter the new era of Model Based Systems Engineering (MBSE), we are excited to utilize these new tools with even greater success than before. The possibilities of democratizing analysis with our simulation tools will offer tremendous value to our products in meeting schedules and addressing engineering issues much sooner than later.  

We are also looking closely at Simulation Embedded Design (SED) on the unified platform. Using this, combined with Templates and Knowledgeware, helps us drive Simulation Driven Designs (SDD) up front in the process of product development. Another aspect is the possibilities to do real-time simulation, combined with photorealism, so customer feedback and can be incorporated before making parts. Combine that with the future of doing augmented reality/virtual reality (AR/VR) capabilities and the future looks extremely exciting for us.

When did you join COE and what has been most valuable to you as a result of your membership?

I have been personally involved with COE for over 24 years now. I volunteered as a chairman for Kinematics and Multibody Dynamics within the Engineering, Analysis & Simulation (EAS) track. I was later recruited to lead the EAS Division as a manager.

Over my tenure with COE, I have seen the analysis capabilities grow from linear FEA and basic Kinematic tools, to a full portfolio of analysis tools which includes linear/nonlinear FEA, optimization, kinematics, Multi-body Dynamics, Fluid Dynamics, controls, etc. The tools combined with new process composers hold great promise and value to companies like ours. Democratization of analysis is a going to be a great boom to engineering design. We’ve already seen the benefits of many these tools today as we incorporated Dassault Systèmes’ and partner solutions with great success on the 737 Max, 747-8, 777x and, of course, the 787 airplane programs. Cycle times have been reduced and a common PLM platform has meant less learning of the tools and more focus on the engineering of our products.
