Abstract

The invention discloses a parallel vector propulsion mechanism of an autonomous underwater vehicle. The parallel vector propulsion mechanism comprises a static platform and a mobile platform, wherein a propeller main motor is arranged on the static platform, a propeller drive shaft system is arranged on the mobile platform, three groups of branch chains are arranged between the static platform and the mobile platform and consist of two groups of six-degree-of-freedom UPS driving branch chains and one group of two-degree-of-freedom U-shaped branch chains, the static platform, the mobile platform and the three groups of branch chains form a two-degree-of-freedom spherical three-link parallel mechanism, and the two-degree-of-freedom U-shaped branch chains are fixedly connected with the mobile platform and are perpendicular to a plane of the mobile platform; an SPS transmission branch chain is also arranged between the static platform and the mobile platform, and is used for transferring the torque and motion of the main motor into the propeller drive shaft system. The parallel vector propulsion mechanism has the advantages of being good in low-speed steering performance, high in rigidity, high in motion precision, high in motion response speed, and the like.

Description

technical field [0001] The invention relates to the field of marine exploration tools, and more specifically, relates to a thruster structure of an AUV. Background technique [0002] AUV is a kind of underwater robot. It is a cable-free underwater robot. It is customarily called an autonomous underwater vehicle (Autonomous Underwater Vehicle, AUV). With the continuous expansion of the scope of AUV applications, designers have put forward higher requirements for AUV's underwater operation task capability and complex environment adaptability, especially for AUV maneuverability and mobility. In this context, the traditional fin-rudder control method can no longer meet the complexity and flexibility requirements of AUV's underwater movement to a certain extent. Propulsion devices are one of the effective solutions. Vector propulsion is also called thrust steering technology, which means that the propulsion system of a space moving object can provide propulsion in the direction...
