Track: Engineering Analysis & Simulation

501 (AS): Chilling Out With Simulation

Rick Marickovich, Raytheon Aircraft Co. Keeping systems cool in aircraft equipment bays can be a challenge. Our advance Design group was tasked to resolve one such issue on the Hawker 4000 aft equipment bay. This session will demonstrate how using CATIA V5 with our analysis tools we were able simulate a complete system and generate a solution. It will detail CATIA V5 modeling and parameterization linked with USM3Dns to perform the analysis and verify the solution. This was accomplished without any physical mockups or parts. The final test being production flight test verifying that the simulated system performed properly.

502 (AS): Augmented Reality Based Visual Prototyping: See What You Mean

Neil Littell, Center for Advanced Vehicular Systems at Mississippi State University This presentation will demonstrate how users can leverage free augmented reality technologies to breathe new life into their models with minimal effort. This simple process uses generic CATIA 3dxml files to display models within the context of the user’s actual environment. Potential applications for this technology include: virtual manufacturing, prototyping, training and product inspection. Following an interactive demonstration, the application of augmented reality technology will be detailed from start to finish for COE members to replicate at their facility.

503 (AS): Associative Topology Optimization in the Structural Design and Analysis Process

John Vandeventer, The Boeing Company Flint Jamison, The Boeing Company  An overview of topology optimization in the structural design and analysis process will be followed by a live demonstration of the Altair Hypershape CATIA tool using a realistic aerospace design and analysis scenario. The overview will describe topology optimization of a product and discuss the advantages it provides to the design process. The live demonstration will provide the audience with an example of a realistic topology optimization scenario using the Hypershape CATIA tool which is directly integrated with the Optistruct topology optimization tool. The demonstration will take place in and emphasize the use of CATIA in the topology optimization process.

504 (AS): How to Perform Advanced Simulations Inside the V5 Environment

Jon Wiening, SIMULIA This presentation demonstrates the depth and maturity of V5 simulation by stepping through several industry-focused analysis workflows. It details specific automotive FEA simulations performed using Abaqus for CATIA V5, including the following: static stress simulations involving plasticity and rubber materials, high-speed dynamic simulations on energy-absorbing components, thermal-stress simulations on surfaces subject to heat dissipation through friction, as well as stress simulations on assemblies with large displacements through mechanism motion.

505 (AS): Standards for Simulation Data Management

Vijay Srinivasan, IBM Corporation Simulation Data Management (SDM) is an emerging area of importance that impacts the way simulation data is managed and the simulation processes are integrated with other engineering and business processes in industry. It has already been compared and contrasted with the more established Product Data Management (PDM) systems. This has also prompted standards development organizations and consortia (such as ProSTEP iViP and PDES Inc) to undertake projects to define standardized data models and process elements for engineering analysis and simulation. In this talk I will outline some of these emerging standards, and their current and potential impact on SDM.

506 (AS): Solving The "Missing Linkage" (4-Bar Linkage)

Jeffrey Roark, Johnson Controls Four-bars are simple mechanisms common in mechanical engineering machine design and fall under the study of kinematics. The difficulty in designing a four-bar mechanism is due to the given design constraints, OEM packaging or internal engineering rules. During this session we will look at how the use of Knowledgeware can be used to solve the "Missing Linkage" problem.

507 (AS): Advanced Kinematic Analysis on 747 Aircraft Landing Gear

Jacob Virnig, Boeing To meet FAA requirements aircraft landing gear must be able to deploy under gravitational forces without powered assistance. On the new Boeing 747-8 program an analytical method was required to predict impact loads between the landing gear and the landing gear doors during such an event. An advanced kinematic simulation was created in LMS Virtual.Lab-Motion to perform a multibody dynamic analysis. The analysis was used to predict the impact loading to the main landing gear on the main gear doors to correlate with actual factory test data used to validate the new design.

508 (AS): Advanced Force-feedback Solutions and Their Applications

Pierre Vercruysse, HAPTION In this paper, we describe how the emergence of industrial applications of haptic technologies, and more specifically of force-feedback devices, opens new perspectives. First, we describe recent breakthroughs of force-feedback solutions for interaction with the digital mock-up in Virtual Reality. We present the principles of force-feedback, starting with remote manipulation such as in the nuclear industry, and following with interactive real-time physic simulation in a CAD environment. Then, we explain how those solutions help reduce design time and costs, and improve quality and maintainability of the future products. We give precise examples and success stories coming from major automotive and aerospace manufacturers, outlining the benefits as reported by the users. Finally, we focus on potential applications on different area.

509 (AS): Validating Structural Fidelity Concurrently With Design: Ship and Heavy Structures

Nilothpaul (Neil) Dutta, Dassault Systèmes of Americas Corporation Abstract: This session will discuss and demonstrate the latest in CATIA breakthrough technologies for morphing design and engineering validation in a ship structures context concurrently on the same interface. The exact solution is valid for all structural applications across industries. Description: As CAD solutions saturate the market, high stakes in major projects depend on the engineering soundness of the product models. Most structural applications need to pass classification society tests to be finalized for manufacturing. While 3D accuracy is key to space and interference management, the engineering analysis results are often performed ‘over the fence’ by different groups using discordant tools and methodologies. Innovation and creativity is often compromised due to the lack of realistic simulation. This results into over or under designing a high budget product. Globalization and outsourcing of the manufacturing processes compensates somewhat for the cost. This however, compromises on the competitive advantages of established corporations and design houses. The advantage of designing right the first time and then reusing existing models for modifications and swift reanalysis is a key for companies to stay ahead in the game. Not only does it shorten the design spiral, but also fosters innovation and empowers the designers & engineers to influence one another concurrently and constructively. What used to be difficult to explain due to usage of different software and groups can get simpler through a common interface, enabling & encouraging the corporation to speak a common holistic language. This session will demonstrate the design and analysis of a high-impact product using various CATIA disciplines: -.Structures design process (using SFD/SDD)  -.Engineering Analysis (using GAS/GPS/Abaqus)  -.Fast Redesign based on results from above. -.Collaboration (using 3DXML)  Participants will see firsthand the ability of the CATIA to bring about Business Transformation in the creation of industrial / ship structures, and the resultant time savings from the adoption of this solution set.
