Structure-Borne Traveling Waves (SBTWs) have significant promise as a means of underwater propulsion, solid-state motion, and drag reduction. However, there is limited understanding over how to tailor SBTWs for these applications. This study establishes guidelines and a procedure for tailoring SBTWs on thin-walled two-dimensional (2D) surfaces. These guidelines were specifically crafted to yield SBTWs favorable for propulsion and solid-state motion: propagation along a uniform direction and with consistent amplitude. SBTWs are steady-state traveling waves generated by taking advantage of a surface’s modal properties (i.e. mode shapes). This novel mechanism provides significant benefits including a minimal actuation footprint, a wide frequency bandwidth, and active variability (propagation direction, wavelength, etc). However, this mechanism also introduces a dependence on the mode shapes and actuator location. Thus, to tailor SBTWs favorable for propulsion the relationship between SBTWs, the mode shapes, and actuator locations must be understood. Eight Guidelines governing this relationship are established. These Guidelines are demonstrated using SBTWs generated on a previously validated model of a 2D plate. Among others, it is shown that the frequency bandwidth can be broken into distinct frequency regions, and each region can be classified as yielding favorable or unfavorable SBTWs. A multi-step procedure is then introduced that enables SBTWs to be tailored on any thin-walled surface. Numerically or experimentally applicable, the actuator configuration can be defined to tailor SBTWs with a specific propagation direction; all that is required is knowledge of the mode shapes. Finally, a case study is presented in which the guidelines and procedure are implemented to tailor SBTWs on a trapezoidal surface. Two different sets of SBTWs are tailored, each propagating in different directions and with various wavelengths. Thus, the established guidelines and procedure enable SBTWs to be tailored for specific applications, such as propulsion and solid-state motion.

结构波的行进波（SBTW）作为水下推进，固态运动和减阻的一种手段具有重大前景。但是，对于如何为这些应用程序定制SBTW的了解有限。这项研究建立了在薄壁二维（2D）表面上裁剪SBTW的准则和程序。这些准则经过专门设计，可产生有利于推进和固态运动的SBTW：沿均匀方向传播且振幅一致。SBTW是通过利用表面的模态特性（即模态形状）生成的稳态行波。这种新颖的机制具有显着的优势，包括最小的驱动足迹，宽的频率带宽以及有效的可变性（传播方向，波长等）。然而，这种机制还引入了对模式形状和执行器位置的依赖。因此，为了定制有利于推进的SBTW，必须了解SBTW，模式形状和致动器位置之间的关系。建立了八种指导这种关系的准则。使用在先前验证的2D平板模型上生成的SBTW演示了这些准则。其中，示出了可以将频率带宽划分成不同的频率区域，并且可以将每个区域分类为产生有利或不利的SBTW。然后引入了一个多步骤过程，使SBTW可以在任何薄壁表面上进行定制。在数值上或实验上适用，可以定义执行器配置，以调整具有特定传播方向的SBTW。所需要的只是了解模式形状。最后，介绍了一个案例研究，其中实施了指导方针和程序以在梯形表面上定制SBTW。量身定制了两组不同的SBTW，它们分别沿不同的方向和不同的波长传播。因此，既定的指南和程序使SBTW能够针对特定应用（例如推进和固态运动）进行定制。
