Abstract
Low-gravity passive balance technology is widely used in astronaut adaptive training. Among them, the series-spring parallelogram mechanism is a basic mechanism in the passive balancing device. We propose a adjustable spring parallelogram device. Compared with the previous devices, it is easy to adjust and can realize the balance of gravity according to different situations. Theoretical analysis is utilized to design this parallelogram mechanism with parallel springs in series, then both the different weight balance experiments and numerical simulation of impact load in ADAMS verify that the mechanism has the characteristics of low gravity balance. This provides a theoretical basis and application basis for the design of adaptive training devices for astronauts on the ground.
