Abstract
Low-gravity passive balance technology is a technology widely used in astronaut adaptive training. Among them, the series spring parallelogram institution is a basic institution in the passive balancing device. A parallelogram institution with series springs is studied in this paper. Firstly, the three-dimensional parallelogram institution model of the series spring is built by Solidworks and is imported into ADAMS. Secondly, the dynamic simulation of the institution under impact load is performed in ADAMS, and the parallelogram rotation angle θ in the parallelogram institution, the spring stiffness coefficient k and the spring installation position in the series spring parallelogram are respectively changed in the simulation. Finally, the simulation results show that the institution has stable gravitational balance characteristics when other initial parameters remain unchanged. This provides data support for the design and manufacture of adaptive training devices for astronauts on the ground.
