기계요소의 설계해석방법을 중점적으로 학습한다. 기계요소에 작용하는 하중, 응력, 변형해석방법과 재료선정, 정하중 및 피로하중 조건에서의 파괴이론, 파괴역학 적용방법 등 기초 설계이론을 고찰하고 이를 볼트체결부, 용접부, 축, 베어링, 기어, 스프링 등 주요 기계요소들의 설계해석에 적용한다. 한편, 공학설계팀 project를 시작하여, 시스템설계II와 연계하여 완성한다. 시스템설계I에서는 그룹별로 설계문제를 정의하고 개념설계안을 도출하는 것을 목표로 하며, 주어진 문제에 대한 design competition도 벌인다.
Study the design analysis method of the mechanical elements and the basic design theory including load design based on material selection, stress and deformation analysis, fracture theory, and fatigue theory. Apply major mechanical elements such as joining, welding, shaft, bearing, gear, spring, as well as thermo and fluid elements, to design analysis. Start the ‘engineering design team’ project and complete it continuing to System Design II (MECH 433)
