Mono-shell submarine's acoustical coating is supposed to possess the multifunctional characteristics of mechanical noise, hydrodynamic noise and acoustic target intensity control. Two difficulties need to be addressed for this purpose: the first one is to improve the mechanical noise low-frequency control effect; the other one is to achieve multifunctional compatibility of acoustical coating. In this paper, from the perspective of reducing the sound radiation of mechanically excited shells, modal superposition method was adopted to establish the vibro-acoustic coupling and sound radiation model of multilayer graded acoustical coating and finite length ribbed cylindrical shell in ideal aqueous medium of infinite size. Based on the acoustic coating modal transfer function characteristics, the acoustic coating gradient distribution characteristics, thickness, the number of layers and other parameters were analyzed to reduce sound radiation of the ribbed cylindrical shell. The characteristic acoustic impedance asymptotic parameter distribution of the layered gradient acoustic cover was given and compared with the sound reduction characteristics of laying a uniform acoustic cover. The results indicate that the acoustic coating with increased acoustic impedance and slow wave velocity from the inner to the outer layer of the ribbed cylindrical shell has the property of reducing the vibration displacement of the outer surface more effectively than the uniform coating, which can significantly increase the sound reduction effect and extend the low frequency range of noise reduction. Optimisation of the acoustic coating should increase the acoustic impedance mismatch of the inner layer and the outer layer adaption effect, in order to help reduce the low frequency acoustic radiation of the ribbed cylindrical shell and to take the reduction of the acoustic target intensity into account.

单壳体潜艇敷设声学覆盖层应具有机械噪声、水动力噪声和声目标强度控制的多功能特性,为此需要解决两个基本问题:其一,提高机械噪声低频控制效果;其二,实现覆盖层的多功能兼容性。本文从降低机械激励壳体声辐射角度出发,采用模态叠加法,建立无限大理想水介质中分层梯度声学覆盖层与有限长加肋圆柱壳的声振耦合及声辐射模型,基于声学覆盖层模态传递函数特性,计算分析声学覆盖层分层梯度分布及厚度、层数等参数对加肋圆柱壳辐射噪声影响的特征和规律,给出分层梯度声学覆盖层的特征声阻抗渐变参数分布并与敷设均匀声学覆盖层降噪特性比较。研究结果表明:加肋圆柱壳敷设内层至外层声阻抗逐渐递增,各分层取慢波速的声学覆盖层,具有比均匀声学覆盖层更有效地降低外表面振动位移的特性,可明显增加降噪效果,并扩展低频降噪范围。声学覆盖层的优化应增加声阻抗的内分层失配和外分层适配的效应,有利于降低加肋圆柱壳低频声辐射,并可兼顾降低声目标强度。

单壳体潜艇敷设声学覆盖层应具有机械噪声、水动力噪声和声目标强度控制的多功能特性,为此需要解决两个基本问题:其一,提高机械噪声低频控制效果;其二,实现覆盖层的多功能兼容性。本文从降低机械激励壳体声辐射角度出发,采用模态叠加法,建立无限大理想水介质中分层梯度声学覆盖层与有限长加肋圆柱壳的声振耦合及声辐射模型,基于声学覆盖层模态传递函数特性,计算分析声学覆盖层分层梯度分布及厚度、层数等参数对加肋圆柱壳辐射噪声影响的特征和规律,给出分层梯度声学覆盖层的特征声阻抗渐变参数分布并与敷设均匀声学覆盖层降噪特性比较。研究结果表明:加肋圆柱壳敷设内层至外层声阻抗逐渐递增,各分层取慢波速的声学覆盖层,具有比均匀声学覆盖层更有效地降低外表面振动位移的特性,可明显增加降噪效果,并扩展低频降噪范围。声学覆盖层的优化应增加声阻抗的内分层失配和外分层适配的效应,有利于降低加肋圆柱壳低频声辐射,并可兼顾降低声目标强度。

Mono-shell submarine's acoustical coating is supposed to possess the multifunctional characteristics of mechanical noise, hydrodynamic noise and acoustic target intensity control. Two difficulties need to be addressed for this purpose: the first one is to improve the mechanical noise low-frequency control effect; the other one is to achieve multifunctional compatibility of acoustical coating. In this paper, from the perspective of reducing the sound radiation of mechanically excited shells, modal superposition method was adopted to establish the vibro-acoustic coupling and sound radiation model of multilayer graded acoustical coating and finite length ribbed cylindrical shell in ideal aqueous medium of infinite size. Based on the acoustic coating modal transfer function characteristics, the acoustic coating gradient distribution characteristics, thickness, the number of layers and other parameters were analyzed to reduce sound radiation of the ribbed cylindrical shell. The characteristic acoustic impedance asymptotic parameter distribution of the layered gradient acoustic cover was given and compared with the sound reduction characteristics of laying a uniform acoustic cover. The results indicate that the acoustic coating with increased acoustic impedance and slow wave velocity from the inner to the outer layer of the ribbed cylindrical shell has the property of reducing the vibration displacement of the outer surface more effectively than the uniform coating, which can significantly increase the sound reduction effect and extend the low frequency range of noise reduction. Optimisation of the acoustic coating should increase the acoustic impedance mismatch of the inner layer and the outer layer adaption effect, in order to help reduce the low frequency acoustic radiation of the ribbed cylindrical shell and to take the reduction of the acoustic target intensity into account.

单壳体和双壳体作为潜艇的两种主要结构形式,虽然在阻力、航行、安全、抗沉等总体性能方面各具特点,但是,随着航速及机动性要求的提高,单壳体潜艇在中高航速下水动力噪声较低等优势有所凸现,有可能成为安静化潜艇发展的必然选择。一方面,从声学角度来讲,双壳体潜艇存在轻外壳易于受湍流边界层脉动压力激励产生水动力噪声的不利因素;另一方面,却能在耐压壳外表面、轻外壳内表面敷设声学覆盖层,实施多重声振隔离降低辐射噪声,并兼顾声目标强度控制的有利条件。单壳体潜艇为了降低声目标强度,一般只能在耐压壳外表面敷设声学覆盖层,需要兼顾艇内机械系统激励和表面湍流激励产生的辐射噪声控制,也就是说,单壳体潜艇敷设的声学覆盖层应具备机械噪声、水动力噪声和声目标强度控制的多重声学功能。
加肋圆柱壳是反映潜艇壳体结构声学特征的典型模型[1],Burroughs等[2-3]采用Fourier变换方法建立了双周期环肋加强的无限长圆柱壳耦合振动和声辐射模型,并分析不同方向激励力产生的声辐射特性。为了模拟更接近于实际的潜艇壳体结构,文献[4-6]则采用模态法建立了环肋加强的有限长圆柱壳耦合振动和声辐射模型,并将环肋扩展为纵肋的有限长圆柱壳耦合振动和声辐射模型[7]。针对双壳体潜艇结构,文献[8-10]则研究了有限长加肋双层圆柱壳受径向点激励的振动和声辐射特性。众所周知,在弹性板壳结构上敷设粘弹性阻尼层是有效降低船舶结构水下声辐射的基本方法,早期采用无限大和有限大弹性平板模型研究粘弹性阻尼层的降噪特性[11-13],并发展为单向加肋与双向正交加肋的有限大弹性平板声辐射模型[14-16]及非均匀敷设粘弹性阻尼层的弹性平板声辐射模型[17-18]。为了更有针对性地研究粘弹性阻尼层的降噪效果,Cuschieri等[19-20]采用复阻抗参数建立全部和局部敷设粘弹性阻尼层的无限长圆柱壳声辐射计算模型,研究敷设声学层对降低远场声辐射的作用及机理。Ko等[21]还求解弹性体纵波和横波波动方程,研究无限长圆柱壳敷设声学层降低壳体附近的声呐自噪声特性。Harari和Sandman[22]进一步采用能量法求解有限长粘弹性夹心复合结构圆柱壳受激振动和声辐射,计算分析辐射阻尼与结构阻尼的降噪特性。Laulagnet和Guyader[23]忽略柔性层的质量效应,采用复刚度参数表征柔性层声学特性,建立敷设柔性层的有限长圆柱壳声功率计算模型,并研究有限长圆柱壳沿周向部分敷设柔性层的降噪效果[24]。应该说,复动刚度表征柔性层是一种近似的局部阻抗模型,为了更好模拟柔性层的弹性作用,Laulagnet和Guyader[25]采用严格的弹性理论求解柔性层振动,建立更完善的敷设柔性层的有限长圆柱壳辐射声功率计算模型,计算结果表明,弹性理论模型与动刚度模型计算结果基本一致,但柔性层刚度和质量参数对声辐射影响的特性更明确。在圆柱壳周向不完全敷设柔性阻尼层模型的基础上,文献[26]进一步建立了圆柱壳轴向不完全敷设柔性阻尼层的声辐射模型。实际上,粘弹性阻尼层不仅增加了圆柱壳结构质量和阻尼,而且降低了圆柱壳外表面上粘弹性阻尼层辐射面的振速,两种机理都起到降低声辐射的作用,但圆柱壳表面不完全敷设粘弹性阻尼层所产生的“声学窗口”会明显减弱降噪的效果。无论是弹性平板模型还是弹性圆柱壳模型,上述研究一般都是采用均匀材料层的复刚度或严格弹性理论表征粘弹性阻尼层的声学特性及作用。文献[10]针对双层加肋圆柱壳结构建立的声振耦合模型,考虑了轻外壳内外表面及耐压壳外表面的声学覆盖层,并在计算分析均匀材料声学覆盖层降噪特性的基础上,基于水声管声阻抗测量结果,进一步采用分层模型模拟实际声学覆盖层的声学特性,计算验证了声学覆盖层的降噪效果,但是尚未从提高降噪效果的角度研究声学覆盖层分层声阻抗的优化分布。
近年来,为了提高壳体结构声学性能及其环境适应性,功能梯度材料复合结构已成为水下结构振动和声辐射研究的一个热点。文献[27-30]基于弹性壳体理论及Rayleigh-Ritz法,建立了功能梯度材料复合结构壳体振动方程,分别研究振动及频散特性;文献[31-32]则研究了功能梯度材料圆柱壳结构声辐射特性;文献[33]进一步建立了功能梯度材料的回转壳体振动和声辐射模型,计算分析壳体结构材料的杨氏模量等参数在金属与陶瓷属性之间分层变化对声辐射的影响。这些功能梯度材料研究侧重圆柱形和圆锥形等壳体本身的声辐射特性研究,并没有针对声学覆盖层的分层特性进行研究。文献[34]则将均质声学覆盖层扩展为功能梯度声学覆盖层,基于有限元法建模,计算声学参数梯度变化对覆盖层吸声性能的影响规律,但尚未建立梯度覆盖层与圆柱壳耦合的声辐射模型。
本文针对敷设多功能声学覆盖层的加肋圆柱壳,从降低机械激励壳体声辐射角度,考虑浸没在无限大理想水介质中的加肋圆柱壳外表面敷设分层梯度声学覆盖层,建立加肋圆柱壳与分层梯度声学覆盖层及外场声场的声振耦合及声辐射计算模型,基于声学覆盖层的模态传递特性,侧重计算分析声学覆盖层空间梯度分布和慢声速等参数,对降低加肋圆柱壳辐射噪声的特征和规律,提出可有效提高降噪效果的分层梯度声学覆盖层的特征声阻抗参数,从一个侧面明确能够有效降低壳体声辐射的多功能声学覆盖层应具有的声阻抗或声传递特性,为提高声学覆盖层低频降噪性能提供理论依据。
建立如图1所示的有限长加肋圆柱壳数理模型,壳体内表面环向分布一系列周期性加强筋,外表面敷设分层梯度的粘弹性覆盖层,模型浸没在无限大理想水介质中。

声学覆盖层敷设在圆柱壳外表面,一般情况下其弯曲刚度小于圆柱壳体弯曲刚度,可以认为声学覆盖层随圆柱壳体一起振动,具有与圆柱壳相同的周向、轴向波数。按照功能梯度材料的一般声学模型[37-38],假设分层梯度覆盖层由多层均匀材料组成,其中第i分层的密度为,声速为,内外半径分别为riri + 1,第i分层的声压为,相应的模态声压表达式为

依据上一章所建立的数学模型,取表1所列的计算参数,在单位点激励下计算分析圆柱壳模态阶数的选取对辐射声功率收敛性的影响。nm分别为圆柱壳周向、轴向阶数,分别选取(20,80)、(40,150)、(60,170)的模态阶数计算得到的辐射声功率结果如图2所示,在周向阶数和轴向阶数分别为40、150时结果已趋于收敛,因此后续计算中选取(40,150)的模态阶数可以得到较为准确的结果。
根据选定的模态阶数,分别计算无声学覆盖层加肋圆柱壳辐射声功率及均匀声学覆盖层模态声阻抗,经验证与文献[1040-41]的结果一致。在此基础上,考虑加肋圆柱壳敷设声学覆盖层,并取声学覆盖层与水介质特性阻抗一致,圆柱壳结构阻尼因子为0.005,不考虑覆盖层阻尼的影响。计算得到的无声学覆盖层和敷设水层覆盖层的加肋圆柱壳辐射声功率基本吻合,参见图3(a),但设置水层时的辐射声功率高频存在若干峰值,这是由于水层覆盖层将外部无限水介质空间变为轴向有限空间,覆盖层轴向共振引起高频峰值。若将覆盖层厚度由5 cm减薄至1 cm,辐射声功率吻合程度增加,参见图3(b),从而验证了计算模型的精度及合理性。
将校核后的计算模型用于计算分析敷设均匀声学覆盖层对辐射声功率的影响。考虑实际激励力的特征,选取的机械激励力在50 Hz以下频段为常数,在50 Hz频段以上激励力幅值与频率的四次方成反比下降。计算模型基本参数见表1,声学覆盖层厚度取为10 cm,其特征声阻抗ρccc采用水介质特征声阻抗ρ0c0进行归一化ρccc/ρ0c0 = α,取α = 0.5、0.15、0.05,并在声学覆盖层特征阻抗一定时,设置声速cc减小、密度ρc增大,使声学覆盖层归一化声速cc/c0和归一化密度ρc/ρ0满足αc × αρ = α,相应的计算参数见图4表2
依据表1表2给出的参数计算得到的辐射声功率如图5所示。均匀覆盖层归一化特征声阻抗为0.5(Case 1.3),相应的密度取为1000 kg/m3,声速取为750 m/s,在200~1000 Hz频率范围,敷设声学覆盖层的辐射声功率与无声学覆盖层的情况相比,局部频段噪声有所降低,在1200 Hz以上频段则降噪明显。若均匀覆盖层密度不变、声速减小,归一化特征声阻抗分别为0.15(Case 2.3)和0.05(Case 3.3)时,前者辐射声功率在400 Hz以上的大部分频段都具有较好的降噪效果,后者则在100 Hz左右以上频段均有明显的降噪效果,参见图5(a)。这表明减小声学覆盖层特征声阻抗有利于降低辐射声功率,特征声阻抗越小,有效降低的频率范围往低频移动。均匀声学覆盖层特征阻抗一定时,同时改变声速和密度,则声速较低的情况(Case 3.3)比声速较高的情况(Case 3.1和Case 3.2)降低声辐射的效果更明显,参见图5(b)。可以说,具有较小的声学层特性阻抗参数及慢波速参数的声学覆盖层,可以在较低频段有效降低加肋圆柱壳辐射声功率,覆盖层声速较覆盖层密度对降噪的作用更大。
针对具有不同声学参数的分层梯度声学覆盖层,进一步计算分析其降噪特性,计算模型的基本参数如表1所示,10 cm厚声学覆盖层分为5层等厚度层,各分层为2 cm厚均匀层。具体计算工况见表3,其中为了对比,Case 4.1~Case 4.2工况的分层归一化特性声阻抗α = 0.332;工况Case 5.1~Case 5.3中取α = 0.01、0.05、0.2、0.5、0.9,由内至外各分层归一化特性声阻抗逐渐增大;工况Case 6.1~Case 6.3中归一化特性声阻抗取α = 0.01、0.03、0.05、0.07、0.09。两种分层梯度情况按厚度加权平均的归一化特性声阻抗分别为0.332和0.05。此外,在声学覆盖层归一化特性声阻抗一定时,类似表2,进一步考虑声学层声速和密度的不同取值。
一般而言,均匀声学覆盖层降低特征声阻抗而使内表面输入声阻抗减小,导致壳体振动增加,其降噪效果主要依赖于传递阻抗特性而局限于高频段。针对厚度一定的均匀声学覆盖层和分层梯度声学覆盖层,计算得到的内外表面输入声阻抗由图6给出。由图可见,除了100 Hz以下的低频外,在整个计算频率范围内,分层梯度比均匀声学覆盖层的输入声阻抗大2个量级左右。由于分层梯度声学覆盖层内外表面声阻抗的增加,一方面增强了覆盖层抑制壳体振动的效应,另一方面相应的覆盖层传递特性也较均匀层有所区别。
由于输入和传递阻抗的不同,计算得到的覆盖层典型模态传递函数幅值如图7所示。由图可见,均匀层与分层梯度层的模态传递函数在1000 Hz以下频段基本相等,且幅值接近于1,表明覆盖层对低频声压传递基本没有影响,且与覆盖层参数特性无关,但在1000 Hz以上频段,存在声压传递放大效应,且分层梯度层放大效应大于均匀层;均匀层与分层梯度层的模态传递函数在整个计算频率范围内都大于1,且前者的明显小于后者的,表明分层梯度层内表面声压传递到外表面振动位移远小于均匀层情况;同样,均匀层与分层梯度层的模态传递函数虽都小于1,但后者比前者更小,可见分层梯度层内表面振动位移传递到外表面声压也会大于均匀层情况。对于均匀层来讲,传递函数表征的内表面传递到外表面的振动位移基本没有变化,高频段还略有放大;分层梯度层的传递函数除了400 Hz以下频段有放大效应外,400 Hz以上频段则远大于1,说明内表面振动位移传递到外表面位移有明显的衰减效应。虽然分层梯度声学覆盖层内外表面的声振耦合关系比较复杂,不像复刚度参数所表征的均匀层单参数变化特性,但由上述分析可知,除了低频有放大现象外,分层梯度声学覆盖层比均匀声学覆盖层更有利于降低外表面振动位移,参见图8。由图可见,均匀层情况下,在200~1500 Hz频段覆盖层外表面振速小于内表面振速,在200 Hz以下和1500 Hz以上频段,两者基本相等,此结果与文献[23]结果一致。分层梯度层情况下,300 Hz以上频段覆盖层内外表面振速差明显大于均匀层情况,在1500 Hz以上频段更加显著,从而有利于降低辐射声功率。
依据表1表3计算得到的辐射声功率如图9所示。由图9(a)可见,分层梯度层与均匀层归一化特征声阻抗同取0.332,且归一化密度和声速均取α1/2时(参见Case 4.1和Case 5.2),在50 Hz以上频段敷设分层梯度声学覆盖层的加肋圆柱壳辐射声功率明显小于敷设均匀声学覆盖层的辐射声功率。若均匀覆盖层与分层梯度覆盖层的归一化特征声阻抗仍取0.332,但只减小覆盖层声速,而密度不变(参见Case 4.2和Case 5.3),在计算频率范围内,敷设分层梯度覆盖层的加肋圆柱壳辐射声功率下降明显,参见图9(b)。在给定覆盖层归一化特征声阻抗的情况下,降低声速有利于降低辐射声功率的结果与敷设均匀层情况一样。进一步针对平均归一化特征声阻抗分别为0.332与0.05的分层梯度覆盖层,选取慢声速参数(参见Case 5.3和Case 6.3),计算的辐射声功率可见图9(c),在200 Hz以下频段两种参数分层梯度覆盖层对应的辐射声功率基本一样,在300 Hz以上频率范围,较小的平均特征声阻抗对应的辐射声功率稍小一些,但没有减小均匀覆盖层特征声阻抗对降低辐射声功率的效果明显。由此可见,采用逐渐增加分层梯度声阻抗,且各层取慢波速的声学覆盖层,可以明显增加降噪效果,并扩展低频降噪范围,图10给出了相应的分层梯度声学覆盖层特征声阻抗及声速和密度参数。这种参数分布也有利于兼顾声目标强度控制。
在分层梯度声学覆盖层平均归一化特征声阻抗及归一化密度和声速相同的情况下,计算声学覆盖层厚度对圆柱壳辐射声功率的影响,分别取覆盖层厚度为5 cm、10 cm、15 cm,均分为等厚度的5层,具体计算参数见表4。由计算得到的辐射声功率(图11)可见,覆盖层厚度由5 cm增加到10 cm,在80~250 Hz频率范围辐射声功率略有降低,在250~2000 Hz的绝大部分频段辐射声功率则降低5 dB左右,声学覆盖层厚度进一步增加到15 cm,在250~2000 Hz频率范围辐射声功率可降低10 dB左右。可以说,增加声学覆盖层厚度可降低高频辐射声功率,但降低低频辐射声功率的作用不明显。
在给定声学覆盖层为厚度10 cm的情况下,进一步比较分层梯度声学覆盖层的层数对加肋圆柱壳辐射声功率的影响,声学覆盖层分为等厚度的5层和3层,分层厚度分别为2 cm与3.33 cm,相应的归一化特征声阻抗分别取为α = 0.01、0.05、0.2、0.5、0.9和α = 0.01、0.75、0.9,平均归一化特征声阻抗均为0.332,具体计算参数如表5,计算得到的辐射声功率如图12所示。分层归一化声速取为α1/4时,分层梯度覆盖层由5层改为3层,300 Hz以下频段辐射声功率变化较小,在300~1000 Hz及1500 Hz以上的大部分频率范围,3层比5层对应的辐射声功率略小一些;分层归一化声速减小为α1/2时,在300 Hz以上频率辐射声功率减小2~3 dB;当归一化声速进一步减小为α时,则3层分层的辐射声功率降低的范围往低频扩展到60~200 Hz,其原因是分层梯度覆盖层层数减少后,内层较低的特征声阻抗的失配作用增大。由此可见,声学覆盖层设计应增加声阻抗内分层失配和外分层适配的效应,有利于降低加肋圆柱壳声辐射。
本文采用模态叠加法,建立了无限大理想水介质中分层梯度覆盖层与有限长圆柱壳声振耦合及声辐射模型,计算分析了声学覆盖层空间梯度分布及厚度、层数等参数,对加肋圆柱壳辐射噪声影响的特征和规律,给出了可有效提高降噪效果的分层梯度声学覆盖层的特征声阻抗渐变参数,研究结果表明:
(1)在加肋圆柱壳外表面敷设的均匀声学覆盖层特征阻抗一定时,选取慢波速覆盖层可以增加覆盖层的降噪效果,并一定程度上向低频扩展降噪范围。覆盖层声速比覆盖层密度对降噪的作用更大。
(2)在厚度一定的情况下,敷设由内至外声阻抗逐渐增大的分层梯度声学覆盖层,由于输入阻抗增加及传递函数改变,一方面增加了壳体振动的抑制作用,另一方面内表面传递到外表面振动位移有明显的衰减作用,相应具有比均匀声学覆盖层更有效地降低外表面振动位移的特性,有利于降低加肋圆柱壳的辐射声功率。
(3)基于分层梯度声学覆盖层的低频声振传递特性,敷设分层梯度覆盖层的加肋圆柱壳辐射声功率,在低频扩展到50 Hz仍具有明显的降噪效果,优于敷设同样厚度的均匀覆盖层的效果;在声学覆盖层平均特征声阻抗一定时,采用逐渐增加分层梯度声阻抗,且减小每分层声速,可进一步增大降噪效果并扩展低频降噪范围。
(4)在分层梯度声学覆盖层平均归一化特征声阻抗及归一化密度和声速给定的情况下,增加分层梯度声学覆盖层厚度可进一步降低高频辐射声功率,但降低低频辐射声功率的作用不明显;给定分层梯度覆盖层的厚度,将分层数由5层改为3层,增大了内层较低特征声阻抗的失配作用,可提高加肋圆柱壳的降噪效果2~3 dB。声学覆盖层的优化应增加声阻抗内分层失配和外分层适配的效应。
在研究分层梯度声学覆盖层降低机械激励的加肋圆柱壳声辐射特性基础上,还需要进一步研究敷设分层梯度声学覆盖层的加肋圆柱壳水动力噪声和声目标强度特性,解决声学覆盖层多功能的兼容性。
