The invention discloses a vibration and noise reduction device and an underwater vehicle, and relates to the technical field of underwater vehicles. The vibration and noise reduction device comprises an elastic beam and a mass block, and the mass block is made of a polylactic acid material. The low-density mass block is adopted, the effective vibration and noise reduction effect can be achieved, and the influence of additional mass on the underwater vehicle is greatly reduced.

    本申请公开了一种减振降噪装置及水下航行器,涉及水下航器技术领域。减振降噪装置包括弹性梁和质量块,质量块采用聚乳酸材料制成。本申请采用低密度的质量块,不但能够达到有效的减振降噪效果,而且大大减小了附加质量对水下航行器的影响。
