The invention discloses an attitude adjustment metamaterial vibration isolator for an underwater vehicle, which belongs to the technical field of vibration control and material engineering, and is characterized by comprising an outer flange body, an inner flange body and a metamaterial vibration isolation part, the outer flange body is a circular ring body with a circular through hole, and a plurality of inner grooves are evenly distributed in the circumference of the inner ring face of the outer flange body. The inner flange body is a circular ring body with a circular through hole, a plurality of outer grooves are evenly distributed in the circumference of the outer ring face of the inner flange body, the outer grooves and the inner grooves are in one-to-one correspondence to form groove cavities, the inner flange body is arranged on the inner side of the circular through hole of the outer flange body in a sleeved mode, and an annular gap is formed between the inner flange body and the outer flange ring. The metamaterial vibration isolation component is formed by periodically arranging metamaterial basic cell elements, and the metamaterial vibration isolation component is arranged in the groove cavity. The vibration isolator can prevent vibration noise from being transmitted to the acoustic sensor, and the sensing and detection capabilities of the acoustic sensor are improved.
