船舶振动ISO 20283-5新标准研究

Research of New Ship Vibration Standard of ISO 20283-5

目前,船舶振动标准越来越严格,而我国船舶企业对振动控制的关注程度还不够。2016年12月提出的新振动评价标准给我国船舶建造水平带来严峻挑战,对船舶企业产生重大影响。将新制定的振动标准ISO 20283-5:2016(E)与当前振动标准ISO 6954:2000(E)进行深入对比,讨论新旧标准的差异,并用新旧标准对实船试航结果进行评估,结果表明目前我国船舶建造水平还不能完全满足新标准的要求。船舶设计与建造人员需要对新标准进行仔细研究,才能提高我国的造船水平,使我国成为真正的世界一流船舶强国。

Currently,the domestic shipbuilding enterprises have not paid enough attention to vibration control of ships,although the ship vibration reduction standard is raised.In December 2016,the new vibration evaluation standard is issued,which brings a significant challenge to shipbuilding capability and a great impact to shipbuilding enterprises in our country.In this paper,the new vibration standard of ISO 20283-5:2016(E)is compared with the old vibration standard ISO 6954:2000(E).The differences between them are investigated.In addition,results of the trial cruise of real ships are evaluated based on the new standard and the old standard respectively.It is indicated that the shipbuilding capability of our country cannot meet the new vibration standard yet.The ship designers and builders still need to study the new vibration standard in order to raise the shipbuilding capability of our country.
