The Digital Meister is an advisory system to help the designer using the knowledge obtained from design and analysis data. In this paper, Taguchi method was applied to analyze the design parameters of automotive engine pulley. As a finite element method (FEM), ALGOR Multi-physics was used for analyzing the static analysis. As a result, two bending positions and material thickness were highly related to the maximum stress. These correlations between design parameters and analysis result will be used for supporting the design process of Digital Meister.

Many companies in mechanical engineering fields have accumulated information of design and manufacturing. The Enterprise Resource Planning (ERP) and Product Data Management (PDM) systems help information gathering and data managing. However, these systems are not flexible to support suitable functionality for specific product because these systems deal with entire enterprise resources. To cope with this issue, a web-based design support system was constructed for the design process of automotive steel pulley. This system provided 1) search service for part design with key word and clustering map, and 2) estimation service of maximum stress. These services reduced design time by reducing iterative jobs with Computer Aided Design (CAD) and Computer Aided Engineering (CAE) for stress analysis, and by enhancing search for existing data of steel pulley.

본 논문에서는 유인과 무인주행이 가능한 전기자동차용 수동 및 자동 조향장치를 제안한다. 기존의 엔진방식의 자동차에 사용되는 자동 조향시스템인 EPS, MDPS는 주행 중에 과부하시엔 핸들 잠김 현상이 발생하는 문제점이 있어 유무인 전기자동차에 적용하는 것은 한계가 있다. 제안하는 수동 및 자동 조향장치는 전자클러치와 풀리를 이용함으로써 수동과 자동변환이 가능하도록 조향 메커니즘을 설계하였다. 제안한 조향장치의 성능을 실험하기 위해 실험용 전기자동차를 제작하고 조향성능을 실험하였다. 실험을 통해 제안하는 수동 및 자동 조향장치는 유무인 전기자동차에 유용함을 확인하였다.
