Opening speech Yasuhiko Fujikawa, President & CEO, VINAS Co., Ltd.
Further reduction of weight and improvements of performance and safety are sought after in automotive and other industrial products. In order to achieve these targets, introduction of design optimization technology and efficient use of software tools are important. This opening speech summarizes use of design optimization technology as a key element in product design process.
Opening session "Challenges, solutions and benefits of structural design optimization"
- Structural design optimization in product development and design in automotive industry - Masami Tsukamoto, Technical Department, VINAS Co., Ltd.
Reduction of weight has been a hot topic in automotive industry in recent years. This presentation introduces you to the latest design optimization methods that enable designs with new materials and shorten development cycles.
- Method of identifying necessary load bearing path for structure optimization
- Method of evaluating new materials (non-linear materials)
- Method of shape optimization to achieve reduction of material use
Technical session "Basics of structural design optimization and effective use of optimization tool"
- What can you do with structural design optimization tools?- Yusuke Houki, Technical Department, VINAS Co., Ltd.
This presentation introduces you how the latest design optimization tools effectively fit into product design process utilizing ABAQUS, Nastran and ANSYS, with a focus on use of TOSCA Structure 6.1, a non-parametric structural design optimization software.
- What features should a structural design optimization tool offer?
- Application examples of non-linear analysis and structural design optimization
- The latest features of structural optimization tools and efficient use of them
Case study session "Current status of structural optimization in European automotive industry"
- Current status in BMW, Audi and TRW - Toru Sugino, Marketing Manager, VINAS Co., Ltd.
This presentation describes application examples in following European automakers and parts manufacturers.
- Structural optimization by Audi
- Study of load bearing path in BMW
- Use of TOSCA and its benefits in TRW
User presentation "Optimization of automotive antivibration rubber parts" Kenichiro Iwasaki, Antivibration rubber technology development department, Testing and analysis unit, Bridgestone Corporation
This presentation by Bridgestone Corporation describes their examples of using TOSCA (non-parametric structure optimization tool) and ABAQUS (FEA software) for design optimization of automotive antivibration rubber parts.
Antivibration parts used in engine mounts and suspension bush are a combination of rubber and metal (BRKT). They support mechanical load and damp and isolate vibration. Rubber portion of such a component must have high damping property and excellent durability, while metal portion must satisfy certain requirements regarding eigenvalues and strength, which makes FEA analysis and design optimization necessary in the development process.
TOSCA can handle non-linear analysis very well, utilize existing mesh generate by 3D CAD or mesher software, and allows automation of optimization loop. In addition to presentation of optimization examples, future challenges will be discussed.
Closing session "Workflow of initial projects of structural design optimization" Toru Sugino, Marketing Manager, VINAS Co., Ltd.
This session describes workflow of an initial project in which scope and objectives of optimization are set, method to achieve them is defined, and quantitative benefits to be obtained is clarified.
