【摘要】 对W12-1海洋平台进行全面的振动测试,按照距离振动最剧烈区域的近远,在底层甲板上布置了6个系列的测点,在中层甲板上布置了2个系列的测点,在平台的4列桩腿上布置了4个系列的测点。对从这些测点采集到的振动信号进行了频谱分析,确定了平台的主振源。以此为基础,提出了对平台进行振动控制的措施。更多还原

【Abstract】 For generally measuring the vibration of w12 - 1 platform,according to the distance from the region vibrating most intensively , six series of measurement points are laid out on the bottom deck,two on the middle deck,and four on the four rows of legs. By analyzing the spectrum of signals from the measurement points, the main vibration sources are ascertained and a solution based on above analysis to the problem is proposed.更多还原
