摘　　要：以降低船用基座辐射噪声为研究背景,选取某型船用基座阻尼板为研究对象,研究不同敷设工艺参数条件下的阻尼板减振降噪效果。采用模态测试方式对不同贴合率、不同厚度和不同规格的阻尼板减振降噪效果进行传递函数测试,为实船基座阻尼板敷设工艺的改进提供支撑。Taken the radiated noise reduction of marine base as the research background,a type of marine base damping plate is selected as the research object to study the vibration and noise reduction effect of damping plate under different laying technology parameters.The transfer function test of vibration and noise reduction effect of damping plates with different joint rate,thickness,and specification is conducted with the modal test,which can provide support for the improvement of actual ship base damping plate laying technology.
