The invention provides an aircraft front undercarriage outer cylinder suspension joint static test fixture. The fixture comprises a rack, an outer cylinder suspension joint assembly, a connection assembly, a diagonal strut assembly and two actuator cylinders; the rack is a cuboid frame and is arranged on a horizontal plane through a base plate; a pair of small beams is arranged on the rack; secondauxiliary beams are embedded inside the small beams; first auxiliary beams for bearing a multi-layer fixing plate assembly are in lap joint with the upper parts of the small beams; an outer cylindersuspension joint is arranged on the multi-layer fixing plate assembly; the outer cylinder suspension joint is hinged to the actuator cylinder on the base plate, a loading point lead-out lug sheet plugged into a loading lever, and the diagonal strut assembly mounted on the second auxiliary beams; and one end of the loading lever is hinged to the actuator cylinder suspended on the rack through an XY-direction small joint, and the other end of the loading lever is connected with a pull sheet arranged on the small beams. With the fixture provided by the invention adopted, the connection conditionand loading condition of a test piece on an undercarriage can be truly reflected, and static and fatigue tests under large load can be withstood.
