The invention discloses a three-dimensional active gravity unloading device suitable for a multi-degree-of-freedom experimental object, which belongs to the technical field of microgravity simulation.The problems that an existing gravity simulation device is poor in motion stability and cannot achieve multi-point hanging can be solved. An electric cylinder type unloading mechanism is fixedly arranged on one second air floating block; a balance weight type unloading mechanism is fixedly arranged on each of other second air floating blocks; a fixed base is fixedly arranged at the lower part ofa force bearing frame; the experimental object and the fixed base are connected through a plurality of connecting rods, every two adjacent connecting rods are hinged, the connecting rods and the fixedbase are hinged, the bottom end of the electric cylinder type unloading mechanism is fixedly connected with one connecting rod close to the experimental object, and the bottom end of each balance weight type unloading mechanism is correspondingly and fixedly connected with one connecting rod. Large-load and long-stroke microgravity simulation is achieved in a hanging mode. The device is driven bya linear motor, multi-point hanging is realized, and the application range of the micro-gravity simulation device is expanded through the combination of two unloading devices.
一种适用于多自由度实验对象的三维主动重力卸载装置,属于微重力模拟技术领域。本发明解决了现有的重力模拟装置运动平稳性差,以及无法实现多点吊挂的问题。一个第二气浮块上固装有电动缸式卸载机构,其余每个第二气浮块上分别固装有配重式卸载机构,承力框架的下部固设有固定基座,实验对象与固定基座之间通过若干连杆连接,且每相临两个连杆之间以及连杆与固定基座之间均为铰接,电动缸式卸载机构的底端与靠近实验对象的一个连杆固接,每个配重式卸载机构的底端各对应固接有一个连杆。通过采用吊挂方式来实现大负载,长行程的微重力模拟。采用直线电机驱动,实现多点吊挂,并同时通过两种卸载装置结合,扩大微重力模拟装置的使用范围。
