  • The analysis of injection molding process by CAE is widely used in development of plastic products. That comes from the fact that CAE analysis can reduce trial and error based on optimized design. On this study, by use of MOLDFLOW, the causes of product defects were found and solved by trade-off study. CAE analysis includes Flow-Cool-Warpage Analyses and finally a new mold-die design with better product quality was suggested. On injection molding of round-shaped plastic fan, new mold-die system with 4-tunnel gates located on the edge of a fan disc shows better quality rather than pin-point gate located on the center of a disc. That was effective in terms of flow mark removal and flatness improvement of the product.

  • For an engineering analysis to predict a bending of PCB by heat, geometry information from CAM data should be transferred to CAE system. But because this work is done by people, not computer, in PCB manufacturing company, it takes too much time, makes many errors and a result is unreliable. To solve these problems, we analyze a working process of company, then develop a CAM to CAE interface to translate a CAM data into a data to be input into a CAE system automatically.

  • 전자산업이 고도화되어감에 따라 전자기술은 소재 . 기계분야와 복합된 기술의 발전이 가속화 되어 가고 있다. 특히 이 글에서는 응력해석 CAE 기술이 전자부품산업에 적용되는 사례를 소 개하고자 한다. 그 중 하나는 하드디스크의 정밀부품 중의 하나인 스핀들 모터용 Hub의 절삭 가공시 고려하여야 하는 탄성 변형량을 해석하고 이를 적용하는 사례이고 또 하나는 Audio Deck의 Capatan Shaft를 지지하는 플리스틱 Base가 신뢰성 시험도중 또는 고온 부하시 발생하는 크리프현상을 해석하여 적용하는 사례이다. 이 글에서 소개하는 두 가지 사례는 전자부품산업에 응력해석 CAE를 적용할 수 있는 예들 중 빙산의 일각에 불과할 뿐이고, 이와 유사한 전자부품에 응력해석 CAE를 적용할 수 있다.

  • This paper describes an automated computer-aided engineering (CAE) system for micromachines whose size range 10 to 10$^3$${\mu}{\textrm}{m}$. An automatic finite element mesh generation technique, which is based on the fuzzy knowledge processing and computational geometry techniques, is incorporated into the system, together with one of commercial finite clement (FE) analysis codes, MARC, and one of commercial solid modelers, Designbase. The system allows a geometry model of concern to be a automatically converted to different FE models, depending on physical phenomena to be analyzed, i.e. electrostatic analysis, stress analysis, modal analysis and so on. The FE analysis models are then exported to the FE analysis code, and then analyses are performed. This system is successfully applied to an electrostatic micro actuator.

  • A New environment SENSATION for circuit optimization and statistical analysis has been developed. It provides real time simulation and includes automatic algorithms to assist for reaching optimal solution. Furthermore, statistical analysis environment is presented which aids in Monte Carlo analysis. worst case corner analysis, and sensitivity analysis. These capabilities faciliate the characterization of the effects of several operating conditions and manufacture process paramenters on the design performances. We verify that the proposed methods can obtain the optimal solution of the objective function through several experimental results.

  • A product is designed through the collaboration among engineers in several fields such as design, analysis, and manufacturing. These series of functions are performed repeatedly during the design process. An easy access and exchange of the model data is one of the important elements that help to shorten production development time. Especially, the importance of data exchange between CAD and CAE applications is increasing in the field of verification and estimation of the products. However, information and knowledge of model which is generated by a CAD software cannot be transferred by a function of CAE software, as an exchange of product data between CAD and CAE applications. It causes a delay in design analysis and eventually discourages a designer's effort in improving his design. Therefore, we need to integrate a commercial CAD and CAE applications effectively and to use the same interface on a product model obtained in a distributed environment. This paper shows how to implement a model exchange between CAD and CAE by a web-service and how to provide a communication environment among engineers.
