The invention discloses a five-degree-of-freedom zero-gravity test device, solves the problem that an existing multi-degree-of-freedom mechanical arm cannot realize a ground simulation test, and belongs to the field of ground zero-gravity tests of spacecrafts. The device comprises a horizontal plane three-degree-of-freedom zero-gravity simulation mechanism, a pitching degree-of-freedom zero-gravity simulation mechanism and a rolling degree-of-freedom zero-gravity simulation mechanism. The pitching degree-of-freedom zero-gravity simulation mechanism is arranged on the horizontal plane three-degree-of-freedom zero-gravity simulation mechanism, and the horizontal plane three-degree-of-freedom zero-gravity simulation mechanism and the pitching degree-of-freedom zero-gravity simulation mechanism are connected through a pitching rotating shaft; the horizontal plane three-degree-of-freedom zero-gravity simulation mechanism is used for realizing two-dimensional movement of a test article in any horizontal range and three degrees of freedom of horizontal complete-circle rotation, and a supporting main body of the pitching degree-of-freedom zero-gravity simulation mechanism adopts a ship plate shape and is used for realizing complete-circle rotation of the test article in the pitching direction; and the rolling degree-of-freedom zero-gravity simulation mechanism is used for realizing the whole-circle rolling of the test article around the rolling degree-of-freedom.
