Diesel power plant(DPP) with the medium speed diesel engine is operated under the very severe condition in aspect of load and operating time as compared with the marine diesel generator set. So, minimized vibration level have to be insured for the more stable operation of engine and generator. The vibration of generator set mainly comes from the resonance between the rigid modes by resilient mount or distortion modes by structural stiffness and the excitation forces of engine. Then, avoidance of resonance with structural modification is generally well known. In this paper, the first order vibration in non-resonance range and local vibration modes were investigated by impact test, response/ODS(operational deflection shape) measurement and 3D finite element analysis for the additional reduction of vibration. The proposed countermeasures were actually applied and their final effects were verified through the in-situ measurement.

ISO TC 108/SC 2 산하에 이미 제정된 24 개의 관련 규격이 있으며, 그 중에 현재 4 개의 규격이 개정 심의 중에 있다. 본 논문에서는 FDIS(Final Draft International Standard) 개정 단계에 있는 육상용 증기 터빈 발전기 세트의 회전축 진동 및 비회전부 진동에 관련한 두 규격(ISO 7919-2:1996, ISO 10816-2:1996) 과 2000년 12월 15일자로 개정 완료된 선박 거주구역 및 작업구역의 진동에 관한 규격(ISO 6954:2000)을 개정 전 규격과 비교 설명 하고자 한다.
