민감도를 이용한 수송체 구조물의 진동저감 설계

There are number of techniques controlling the vibration induced by harmonic exci tation from propeller, fan, and engine.Such methods could include the propercontrol of eigenvalue and eiqenvector, application of vibration isolators. and thereduction of dynamic frequency response itself.In this paper. design sensitivityof frequency responses such as displacement and acceleration is computed.
