摘要： 主要应用声振VA ONE软件对大型导管架平台进行噪声研究，将声学计算基本理论方法（有限元方法、边界元方法与统计能量分析方法）应用到平台噪声研究中。考虑到大型导管架平台的特点，分别对平台开场区域和生活工作舱室进行了噪声预报研究。通过计算得出平台甲板的噪声云图，得出超标区域并提出了相应措施；得到了平台生活工作舱室的噪声水平，并对典型舱室提出了两种降噪措施，对比其中降噪措施得出了可行性较强、经济性较好的措施。

Abstract: Acoustic vibration software VA ONE was used to research the noise problems of large jacket platform, and the basic theories and methods of acoustic calculation (finite element method, the boundary element method and statistical energy analysis method) were applied to the platform noise study. Taking the features of the large-scale jacket platform into account, the noise prediction studies of the platform opening area and the living compartments were carried out respectively. Noise contours of the platform deck and the superscalar area were obtained by calculation, and corresponding measures were also proposed. The noise level of platform living and working compartments was obtained, two types of noise reduction measures for the typical cabin were proposed. Through the contrast, a noise reduction measure with stronger feasibility and better economy was found out.
