振动是舰船舱室噪声的源头,本文基于有限元/边界元方法,对约束阻尼结构在舱室模型建立时相关材料参数的设定进行了较系统的研究,建立起对约束阻尼结构进行仿真计算的方法,仿真结果与试验结果吻合较好。因此,对类似结构约束阻尼处理的减振降噪评估分析有较强的参考价值,可以为约束阻尼的优化设计提供有效指导。 Vibration is the source of ship cabin noise. Based on the finite element / boundary element method, the setting of the related material parameters of the constrained damped structure during the establishment of the cabin model is systematically studied, and the simulation of the damped damping structure is established The simulation results agree well with the experimental results. Therefore, it is of great value to evaluate and analyze the damping and noise reduction of the similar structure constrained damping process, which can provide effective guidance for the optimal design of the constrained damping.
