The article presents results of numerical simulation and experimental studies of elastic wedge wave propagation in cylindrical wedges with positive and negative curvature in the 100–600 kHz frequency range. It is shown that wedge waves in such structures have dispersion and their localization at the edge of the wedge is stronger than that of straight wedges. The results of a study for cases where the inner surface of the wedge is bounded by fluids with different viscosities (water, SAE 10W-30 motor oil, 86% glycerol aqueous solution) are presented.

具有不同几何形状的圆柱形金属楔中的弹性波

本文介绍了在100–600 kHz频率范围内具有正曲率和负曲率的圆柱形楔形中弹性楔形波传播的数值模拟和实验研究结果。结果表明，此类结构中的楔形波具有色散，并且它们在楔形边缘处的定位要强于直楔形。给出了楔形物的内表面被具有不同粘度的流体（水，SAE 10W-30机油，86％甘油水溶液）界定的情况的研究结果。
