AI Technical Summary

Technical Problem

Existing multi-degree-of-freedom wave compensation technology struggles to simultaneously achieve high stiffness, high precision, large workspace, and low inertia, and the rope-driven device carries the risk of interference.

Method used

A multi-degree-of-freedom wave-compensated parallel platform is adopted, which combines rigid constraint components with flexible traction components. With the addition of a buffer unit, dynamic compensation is performed using posture sensors and gyroscopes. The platform is stabilized by coordinating rigid and flexible drives through a controller.

Benefits of technology

It achieves a balance between high rigidity, high precision, and large working space, enhancing the platform's load-bearing capacity, reducing the impact of wind and wave loads, and making it suitable for various working conditions.

Abstract

This invention discloses a multi-degree-of-freedom wave compensation parallel platform, comprising a base, a rigid constraint assembly, a motion platform, a controller one, a controller two, a gyroscope, a posture sensor, a buffer unit, and a flexible traction assembly. Each branch, from the fixed platform to the motion platform, consists of a motor, a reducer, ropes, and fixed pulleys. Its operating method is also disclosed. This parallel platform employs a rope-driven rigid-flexible drive, combining the advantages of high rigidity and precision of traditional rigid parallel mechanisms with the advantages of low inertia and a large working space of rope-driven parallel mechanisms. The parallel platform uses a buffer structure to effectively reduce the impact of wind and wave loads on the platform. This invention, employing a rope-driven rigid-flexible drive, has a simple structure and can effectively achieve wave compensation.
