Abstract

The invention provides a swing and rotation multi-degree-of-freedom motion generating platform. The swing and rotation multi-degree-of-freedom motion generating platform includes a structural frame, a cover plate structure, a rotation component, a transmission component and a swing component; the cover plate structure is arranged at the top of the structural frame; the cover plate structure and the structural frame form a structural shell; the rotation component and the transmission component are respectively embedded in the cover plate structure; the swing component is arranged in the structural shell; the rotation component is in driving connection with the transmission component; the swing component comprises at least one set of magnetic field force generating component and electromagnetic direct driving component, a swing beam and a swing beam supporting component; an magnetic control loop is formed between the magnetic field force generating components and the electromagnetic direct driving components; the electromagnetic direct driving components move in a reciprocating manner under the action of the magnetic forces of the magnetic field force generating components; the swing beam is in driving connection with the electromagnetic direct driving components; and the swing beam supporting component is supported at the center position of the swing beam. The swing and rotation multi-degree-of-freedom motion generating platform of the invention has the advantages of simple structure and light weight, and can satisfy requirement of broadband response and precise control of output vibration.

Description

technical field [0001] The invention relates to the technical field of magnetic drive, in particular to a swinging multi-degree-of-freedom motion generating platform. Background technique [0002] The oscillating and rotating platforms can be used in many fields, such as the oscillating test of the workpiece, human body movement equipment, etc. Existing oscillating and rotating test devices or human body movement equipment are usually controlled by motors. This structure leads to the following defects in the existing oscillating and rotating platforms: [0003] 1. Insufficient driving force; [0004] 2. Complex structure installation; [0005] 3. It is not convenient to adjust the driving force and driving force control according to the needs; [0006] 4. Poor drive accuracy; [0007] Due to the above defects, the existing oscillating and rotating platforms are generally unable to meet the demand for precise control of the output vibration.
