Sc. Abstract: To support design decisions in the product development process, companies are increasingly relying on computer aided simulations. However, investments in simulation technologies can not translate directly into benefit without implementing a system able to capture knowledge and value out of each simulation performed. To implement the switch from traditional product development to Simulation Based Design (SBD) and product development, a system that can efficiently manage simulation data is needed. Common situation in industry is to store everything related to simulations in the analyst’s computer or in a shared folder. Currently only CAE (Computer Aided Engineering) departments in aerospace and automotive OEMs are early adopters of SDM (Simulation Data Management) technology. Commercial SDM systems are developed to suits the needs of big enterprises with repetitive processes and product with broadly similar geometries. The cost for deployment and maintenance of this kind of system represents a barrier for small and mid-size companies. The larger companies might not benefit from a system developed and tuned for the needs of the early adopters mentioned above.

  • Development of a Coupling Approach for Multi-Physics Analyses of Fusion Reactors
    Development of a coupling approach for multi-physics analyses of fusion reactors Zur Erlangung des akademischen Grades eines Doktors der Ingenieurwissenschaften (Dr.-Ing.) bei der Fakultat¨ fur¨ Maschinenbau des Karlsruher Instituts fur¨ Technologie (KIT) genehmigte DISSERTATION von Yuefeng Qiu Datum der mundlichen¨ Prufung:¨ 12. 05. 2016 Referent: Prof. Dr. Stieglitz Korreferent: Prof. Dr. Moslang¨ This document is licensed under the Creative Commons Attribution – Share Alike 3.0 DE License (CC BY-SA 3.0 DE): http://creativecommons.org/licenses/by-sa/3.0/de/ Abstract Fusion reactors are complex systems which are built of many complex components and sub-systems with irregular geometries. Their design involves many interdependent multi- physics problems which require coupled neutronic, thermal hydraulic (TH) and structural mechanical (SM) analyses. In this work, an integrated system has been developed to achieve coupled multi-physics analyses of complex fusion reactor systems. An advanced Monte Carlo (MC) modeling approach has been first developed for converting complex models to MC models with hybrid constructive solid and unstructured mesh geometries. A Tessellation-Tetrahedralization approach has been proposed for generating accurate and efficient unstructured meshes for describing MC models. For coupled multi-physics analyses, a high-fidelity coupling approach has been developed for the physical conservative data mapping from MC meshes to TH and SM meshes. Interfaces have been implemented for the MC codes MCNP5/6, TRIPOLI-4 and Geant4, the CFD codes CFX and Fluent, and the FE analysis platform ANSYS Workbench. Furthermore, these approaches have been implemented and integrated into the SALOME simulation platform. Therefore, a coupling system has been developed, which covers the entire analysis cycle of CAD design, neutronic, TH and SM analyses.

All rights reserved. No part of this publication may be reproduced without the written permission of the copyright owner. ABSTRACT This thesis addresses idealisation error control for the nonlinear finite element method. The focus is on accurate failure prediction of mid-size aerospace structures. The objective is the development of technologies that shorten the certification process of new airplanes, by replacing expensive and time consuming testing with reliable calculation methods. The SAFESA (Safe Structural Analysis) approach was applied to the collapse analyses of stiffened metal panels. ABAQUS/Standard was thereby the utilised nonlinear solver. Because the original SAFESA procedure is tailored for linear analyses, the methodology needed an update. The first analysis case is a stiffened panel compression test which was arranged as a lecture demonstration at Cranfield University. The analysis behaviour is highly nonlinear due to the thin-walled properties of the panel. The second analysis investigates an Airbus compression panel. Until failure, the panel behaves geometrically less complicated because the major load bearing parts are thick-walled and bend smoothly. The main research work is the critical analysis of important modelling assumptions concerning the used material model, boundary conditions and geometrical imperfections. In both cases, the method helped to identify idealisation errors and to build a reliable FEM model. In order to deal with the nonlinear error sources, minor extensions to the original method had to be made.

  • Simulation Comparison Between PTC/Creo and Professional CAE
    2017 International Conference on Mechanical and Mechatronics Engineering (ICMME 2017) ISBN: 978-1-60595-440-0 Simulation Comparison Between PTC/Creo and Professional CAE Software Li-xin WANG*, Jun-hui LIU and Lin-kai CHEN School of Mechanical Engineering, Zhengzhou University, Henan Zhengzhou 450001, China *Corresponding author Keywords: PTC/Creo, Mechanism analysis, Structure analysis, Adams, Ansys. Abstract. CAE is an indispensable tool for mechanical design engineers, and is widely used in product development process. This paper discuss the differences and linkages of the two most commonly used mechanism simulation and strength calculation in the design process. For the same model respectively, simulations using PTC/Creo Vs. Ansys and PTC/Creo Vs. MSC Adams are conducted. The results show that PTC/Creo software is simple to use, easy to modify and accurate enough upon the simulation. However, it is a bit rougher and shallower than the professional CAE software .So, for mechanical design engineers, PTC/Creo simulation tools should be preferred, and the profound analysis should be the duty of professional CAE engineers. Introduction With the development and popularization of CAD technology, three-dimensional software design is more and more commonly used in modern mechanical design. At present, the general understanding is that CAD software is responsible for three-dimensional modeling of parts, components and machine assembly, and static interference analysis. Although CAD software also provides integrated CAE tools (mechanism simulation, structural analysis, thermal analysis, etc.). However, most people are accustomed to the simplified model, and export the model to the professional finite element analysis software (Ansys, Nastran, Abaqus) and virtual prototyping software (MSC.Adams, LMS Virtual.Lab, etc.) for analysis.

  • An Evaluation of Associative Interface for Solidworks and ABAQUS/CAE Hung-Peng Li and Goang-Ding Shyu Baker Hughes Inc
    An Evaluation of Associative Interface for SolidWorks and ABAQUS/CAE Hung-Peng Li and Goang-Ding Shyu Baker Hughes Inc. Abstract: In the modern design and manufacturing world, shorter development cycle times are being demanded. In addition, engineers are being asked to perform more analyses and studies to improve their products. To meet the challenge, engineers will seek more ways to increase robustness and productivity. With the continued integration of computational tools, such as the associative import between SolidWorks and Abaqus/CAE, it is possible to analyze and reiterate designs, materials, and structures in a more productive and efficient fashion. With the assistance of the associative interface capability, one can quickly update design changes into the ABAQUS finite element (FE) pre-processing tool with just one click. This associative importing feature allows tremendous time savings and avoids time-consuming repetitions and mistakes in creating new FE meshes and models for newly imported modified geometries and designs. This new capability allows Abaqus/CAE to update the imported geometries in real time and also to retain the majority of FE analysis model features, such as partitions and meshing seeds, contact interactions, applied loads, and boundary conditions. It also provides the advantage of creating multiple FE models with a reasonable effort for parametric or sensitivity studies to account for design and manufacturing variations, for example, the imperfections of eccentricity and ovality on the effect of collapse pressures. A wide variety of completion tools were evaluated. The interfaces and the process of the associative function between SolidWorks and Abaqus/CAE will be shown. The summary and conclusion including pros and cons will be discussed.
