摘要 建立了弹性板-壳-声腔耦合模型,研究弹性板(壳)结构振动与声场耦合的特性,基于板壳振动微分方程,利用模态叠加法求解位移响应,分析结构与声场耦合之后,弹性板-壳-声腔结构的振动产生的声辐射,分别推导弹性板以及圆柱壳受到外载荷作用情况下振动产生声辐射指定外场点的声压级公式;然后根据点源组合原理,探讨有源力噪声控制,并给出算例予以验证。 The vibration and the coupled sound field of a plate-ended cylindrical shell are studied.Based on the mode superposition method,an analytic formulation between the struc-ture and acoustic cavity is developed.The analytic expression of the exterior sound radiation pressure with the force exerted either on the plate or on the shell is calculated.The active force control is easy to realize.
