Vendor Challenge Workshop

Realistic Simulation of a Flexible Mechanism -
Several Approaches By Simulation Software Suppliers


Presented at NAFEMS World Congress
May 22-25, 2007 Vancouver, BC Canada

Lee Krueger, John Vandeventer - Boeing Commercial Airplanes


NAFEMS World Congress 2007 vancouver CanadaA structural/mechanical system analysis/simulation of a basic Preliminary Design (PD) model of a landing gear was proposed for solution to suppliers of analysis and simulation software. The goal of this exercise was to provide NAFEMS World Congress attendees a look at different processes for solving a realistic design/simulation problem using a variety of design and analysis tools.

Each participant was provided basic geometry, energy absorption data and external load data needed to simulate an aircraft landing gear drop test and fatigue test.  The performance criteria for the system, including reaction loads, maximum stress levels, a weight target, were provided to the participants.  Each participant used this information with their preferred design/analysis product simulation tools and processes, to develop their recommended final product that meets the Boeing provided performance criteria. 

The problem solution made use of vendor simulation tools that span the technologies of kinematics, nonlinear finite element analysis, optimization, and multibody dynamics simulation.  The participants presented their solution process, tools and results of their work at a round-table venue that included a question-and-answer segment with the NAFEMS World Congress attendees. 

It should be noted that this exercise was not a competition or a benchmark problem.  Results of the individual analyses were not compared and attempts to show superiority of one application product over another was not permitted.
