统计能量软件AutoSEA应用技术研究

Research on the Application Techniques of AutoSEA

统计能量是一种适合于高频的模块化分析方法,AutoSEA软件代表这一领域的最高发展水平,以一个简单潜艇模型为例,分别从振源排序、传递路径分析和隔振降噪仿真方面对其应用技术进行研究,结果表明该方法很适合船舶方面的隔振降噪技术研究,值得在该领域应用推广。

Statistical energy analysis （SEA） method is a module-based method, which is very statable for high frequency analysis problems. The software AutoSEA represents the topmost progress in SEA. A vibro-aeoustics analysis was done on a simple submarine model. Vibration and acoustical level calculation, vibration source grading, vibration transfer path analyzing and damping imposing effect are performed. Results reveal that this method has application foreground in ship and the software of AutoSEA is valuable to spread.
