- Abstract
The microgravity environment is a common description of the low-level acceleration state existed on space flight, classified into three major categories of disturbances: quasi-steady acceleration, oscillatory acceleration, and transient acceleration. This environment on space station has afforded a unique area for scientific and technological experiments. The estimation of microgravity level on space station is very significant for space station design. Given a space station with configuration of alphabet "T"and a total mass of around 100 ton, the magnitude and distribution of quasi-steady acceleration is estimated. It shows that the magnitude of quasi-steady acceleration is on the level of 1$\mu$g0, attributing mostly fro the gravity gradient effect. The transient acceleration can reach the level of 1000$\mu$g0. The results are helpful for arranging the layout of scientific payloads and designing the flight model during the period of conducting microgravity experiments.
