The invention discloses a microgravity simulation device based on a parallel mechanism, and relates to a microgravity simulation device. The base comprises a fixed bottom plate and a movable platform at one end of the surface of the fixed bottom plate, the movable platform is provided with a driving side movement table, the opposite end of the fixed bottom plate is provided with a driven side movement table, the movement table is designed based on a Stewart parallel structure and comprises an upper platform, a lower platform and six electric telescopic rods hinged between the upper platform and the lower platform, and the six-dimensional force sensor is fixed to the upper surface of the movement table. The fixing tool is installed on the six-dimensional force sensor and used for clamping and positioning a butt joint module, the driving side movement table provides a butt joint target position and releases a butt joint signal, and the driven side movement table conducts microgravity simulation. The device can quickly and accurately carry out follow-up reaction to simulate weightlessness action, and has the characteristics of adjustable structural parameters, maintainability, reusability, capability of carrying out three-dimensional space simulation, no simulation test time limit and high simulation precision.
