Suspended catamaran target boat

A suspended catamaran target boat, comprising a deck, a suspension structure and two buoyancy units, the two buoyancy units are arranged in parallel and spaced apart, and the suspension structure is connected to upper sides of the two buoyancy units, the deck is mounted on the suspension structure;

• the suspension structure comprises at least two suspension assemblies, the at least two suspension assemblies each include an upper base, a lower base and two support rods, the upper base and the lower base are arranged apart in an up-down direction, the upper base is fixedly connected with the deck, and the lower base is fixedly connected with a corresponding buoyancy unit;
• the two support rods are arranged apart along a width direction of the deck, and the two support rods are hinged between the upper base and the lower base;
• the upper base, the lower base and the two support rods form a four-bar linkage mechanism, and a shock absorber and a restricting mechanism are installed between the upper base and the lower base;
• the deck is provided with a main controller, an acceleration sensor and a heel sensor, and the main controller is respectively electrically connected to the acceleration sensor, the heel sensor and the restricting mechanisms of the two suspension assemblies;
• the acceleration sensor is arranged at the front of the deck to detect a gravitational acceleration of a bow section;
• the main controller is preset with an acceleration threshold, and is configured to receive an electrical signal of the gravitational acceleration and compare the gravity acceleration with the acceleration threshold, so as to control the restricting mechanisms to restrict a maximum allowable length of the shock absorbers to a corresponding value when the gravitational acceleration reaches the preset acceleration threshold;
• at least two heel sensors are provided, and the at least two heel sensors are arranged on both sides of the deck along its width direction to detect an heel angle of the deck towards a corresponding side;
• the main controller is preset with an heel angle threshold, and is configured to receive an electric signal of the heel angle, and control the restricting mechanism of the suspension assembly on a corresponding side to restrict the maximum allowable length of the shock absorber to a corresponding value when the heel angle reaches the preset heel angle threshold.
