Abstract

The invention discloses a hydraulic-electric hybrid driven multi-degree-of-freedom platform. The platform adopts a novel hydraulic-electric mechanical cylinder and a hydraulic mechanical cylinder; when the multi-degree-of-freedom platform is under the working condition of resisting the load, the hydraulic-electric mechanical cylinder and the hydraulic mechanical cylinder output energy outwards; and when the multi-degree-of-freedom platform is under the working condition of exceeding the load, the hydraulic-electric mechanical cylinder and the hydraulic mechanical cylinder absorb the load impact and recover the energy. Compared with the prior art, the multi-degree-of-freedom platform has the following advantages: higher load can be borne to adapt to more working conditions; the power-weightratio is higher; the structure is simpler; and the energy can be recovered to achieve higher reutilization rate.

Description

technical field [0001] The invention belongs to the field of hydraulic-electric hybrid drive systems, and in particular relates to a hydraulic-electric hybrid drive multi-degree-of-freedom platform. Background technique [0002] The multi-degree-of-freedom platform is a mechanism that can realize the movement of multiple degrees of freedom in space. In recent years, it has become a research hotspot of various research institutions and the focus of manufacturers. Among them, the six-degree-of-freedom platform is the most representative. The six-degree-of-freedom platform is a parallel mechanism that can realize six-degree-of-freedom movement in space.
