Today most companies are designing their automobile shapes by using 3 dimensional CAD software, CATIA. And they used to design 2 dimensional press dies to do some elastic work on their products, but they are currently trying to make use of dimensional software, Pro-Engineer. In this case, they have to change the 3 dimensional product design data to the proper format data for the following process. This paper will show the data loss and the deformation during data transfer between CATIA and Pro-Engineer, and then suggest a solution for these problems. Product's surface will be automatically placed by automatic press tipping angle setting in CATIA to prevent the product from being stuck in the press die. The 2 dimensional section view which is based on the tipping angle setting is created by Z-map. And, to remove the data loss and the data deformation in pro-Engineer, the product surface are delivered to the next process after it is changed to the 2 dimensional Z-map curves in CATIA. finally, this paper suggests an algorithm to develop the automatic design program for the press layout which regenerates product shape surface from the previous process.

This paper evaluated the structural improvements and new product development of cleaning machines. A cleaning machine was redesigned for structural improvements and new product development using a 3-D design program CATIA. In addition, structural analysis was conducted on the modeled cleaning machine using the ANSYS program. The total deformation, stress and strain were obtained by the pressure change. This result was applied to the new product development of cleaning machines.

In this paper, a research for the knowledge based configuration design software development of a train vehicle has been presented. Parametric design and knowledge based design concepts have been introduced for rapid design changes and analyses using a commercial CAD software, $CATIA^{/circledR}$ Knowledgeware module. Positions and dimensions of door, small window, large window, and number of seats were used as design parameters. It is crucial for train vehicle design because it enables rapid conceptual design by instant configuration changes. The results of this research can be used as one sub module of the multidisciplinary train vehicle design software and provide a basic data for rolling stock behavior and driver cab ergonomics of a train vehicle.

FEM analysis of cleaning machine was performed. A cleaning machine was designed and measured to develop a cleaning machine with highly improved performance and a real configuration. 3D modeling was conducted using the 3-D design program CATIA V5. In addition, FEM analysis was conducted on the modeled cleaning machine using the ANSYS finite element analysis program and the pressure changes in internal fluid flow were visualized. This result was applied to the new product development of cleaning machines.

Designing Trim die block is a complicated and time-consuming process heavily resting on the experience of the designer. To reduce design time and human errors, a knowledge base is used to automated the design process. In this paper, a framework of the Rule-based CAD System is presented for trim die block design consisting of a rule-base, design process control module and geometric modeler (CATIA). The rule-base includes design rules and know-how of design specialist. CATIA is used as the overall CAD environment and rule-base and design control modules are developed by C++ language with an interface to CATIA. Using the rule-base, the designer can explore alternating designs fast by changing design parameters and the part-list is automatically created which avoids miscommunication.

자동차, 조선, 항공 분야 등에서는 3차원 모델러를 이용한 설계작업이 다양하게 이루어지고 있으며 특히 자동차 업계에서는 그 활용도가 대단히 높다. 통상, 완성차 업계에서 작성된 곡면 데이터는 협력업체에서 부품 설계 및 제작에 대단히 중요한 정보가 되기 때문에 이와 같은 곡면정보를 이용하기 위하여 완성차 업체와 동일한 CAD 시스템을 보유하고 있어야 한다. 그러나 완성차 업체에서 사용하고 있는 3차원 모델러(CATIA, Pro/Engineer, 등)는 사용하기가 쉽지 않을 뿐만 아니라 대단히 고가의 장비여서 이를 중소 협력업체에서 구축한다는 것은 현실적으로 매우 어려운 것이 사실이다. 본 고에서는 3차원 모델러 중 자동차 업계에서 가장 많이 쓰이고 있는 CATIA(Dassault사)의 곡면 데이터를 자유로이 응용할 수 있도록 구축한 Jig 설계시스템에 대해 소개하고자 한다.

In this research, design optimization of an aircraft wing has been performed using the fully automated Multidisciplinary Design Optimization (MDO) framework, which integrates aerodynamic and structural analysis considering nonlinear structural behavior. A computational fluid dynamics (CFD) mesh is generated automatically from parametric modeling using CATIA and Gambit, followed by an automatic flow analysis using FLUENT. A computational structure mechanics (CSM) mesh is generated automatically by the parametric method of the CATIA and visual basic script of NASTRAN-FX. The structure is analyzed by ABAQUS. Interaction between CFD and CSM is performed by a fully automated system. The Response Surface Method (RSM) is applied for optimization, helping to achieve the global optimum. The optimization design result demonstrates successful application of the fully automated MDO framework.

The purpose of this study is to extract typical body shapes of Korean adults based on the three-dimensional Korean anthropometric data measured through 5th national anthropometric survey and to examine the suitability of the 3-D human shape data for the interior packaging. 36 three-dimensional anthropometric variables related to the design of vehicle interior were considered for the appraisal of typical body shapes. Four major factors were extracted by the factor analysis and factor scores were calculated for all subjects. Typical or standard drivers of Korean adults were selected by the minimum deviation criteria for the four factor scores with respect to 5th, 50th, and 95th percentiles, respectively. Typical drivers of Korean adults were visualized by the CATIA-HUMAN program due to the absence of proper application software for three-dimensionally scanned human body data. There are considerable differences between the anthropometric data of Korean adults and those provided by CATIA-HUMAN program, which shows that the modeling data provided by CATIA-HUMAN should not be directly applied to the ergonomic evaluation for the vehicle design. This suggests the necessity for the development of suitable software for scanned human shape data. It is also expected that the anthropometric data of typical drivers extracted from this study help design package layouts and improve the suitability of ergonomic evaluation for Korean customers.
