실험실 소개

• 진동이란 탄성을 가진 물체가 반복적으로 흔들리는 것을 말하며, 모터와 같은 구동부를 포함하는 대부분의 기계장치에는 원하지 않는 진동이 발생하게 된다. 이 같은 진동은 대부분의 기계장치의 수명과 신뢰성을 저하시키는 중요한 원인으로 작용한다. 진동 및 측정 실험실은 기계장치 등에서 발생하는 진동을 측정하고 효과적으로 제어할 수 있는 방법에 대해 연구한다. 또, 공작기계 적용을 목적으로 정밀측정에 대한 광범위한 연구를 수행하고 있다. 진동 및 측정 실험실은 진동 및 정밀측정에 대한 이해와 경험을 제공하며, 이를 통해 전통기계산업분야는 물론 ICT 관련 기술개발이나 생산장비 분야 등에 진출할 수 있다는 것이 가장 큰 장점이라 할 수 있다
