如何改进船舶降噪设计,使船舶设计达到国际水平,这是当前船舶设计者面临的一个迫待解决课题.“津油202”轮是日本80年代初的新产品,在设计中如何满足日本1975年7月生效的噪声标准是值得关心的问题.为此我们对该轮进行了噪声与振动测量,试图探讨该轮在降噪设计方面的经验,以供设计新船时借鉴. How to improve the ship’s noise reduction design and make the ship’s design reach the international level is a pressing issue that ship designers are currently facing.Taking the “Jin Oil 202” ship as a new product in Japan in the early 1980s, how to meet the requirements of Japan 1975 The noise standard which came into force in July of this year is a concern, and for that reason we conducted a noise and vibration measurement of the wheel in an attempt to explore the experience of this round of noise reduction design for reference when designing new ships.
