The invention discloses a quasi-zero stiffness metamaterial vibration reduction mounting structure of an underwater vehicle hydrophone, which belongs to the technical field of underwater vehicles, and comprises an oil seal end cover mounted at the front end of a front fairing of an underwater vehicle, a mounting rack fixed at the front end part of the oil seal end cover, and two quasi-zero stiffness vibration reduction components arranged in front of and behind the mounting rack, the outer side parts of the quasi-zero-stiffness vibration reduction components are connected with the mounting frame, concave parts for clamping the end parts of the hydrophone are formed in the middle parts of the quasi-zero-stiffness vibration reduction components, and a mounting space for arranging the hydrophone is formed between the two quasi-zero-stiffness vibration reduction components; and the two ends of the hydrophone are respectively clamped and clamped in the concave parts of the two quasi-zero stiffness damping components. According to the quasi-zero-stiffness metamaterial damping device, through conformal design, vibration attenuation, structure optimization and energy-saving effects, an efficient, stable and low-noise hydrophone installation solution is provided for an autonomous underwater vehicle, and the performance of the quasi-zero-stiffness metamaterial damping device in underwater detection and signal acquisition is remarkably improved.
