Suspended micro-low gravity environment simulation technology: Status quo and prospect

The micro-low gravity environment in aerospace causes different forced states and dynamic performance of the spacecraft and astronauts from those in the ground gravity environment; therefore, it is necessary to simulate this environment on the ground. Several commonly used micro-low gravity simulation methods are reviewed. Among them, the suspension method is widely used because of its advantages of long simulation time, large simulation range, and having no additional inertia. From the perspective of the system scheme principle, the research results of existing suspended micro-low gravity simulation systems at home and abroad are classified and reviewed. According to the requirements of micro-low gravity simulation, two design criteria and three key technologies of the suspension micro-low gravity simulation system are summarized. The research status of these three key technologies is reviewed in detail. The development trends of the system design and three key technologies of the future suspended micro-low gravity simulation are discussed.
