Abstract: The invention discloses a self-centering vector force loading device, and belongs to the field of mechanics. The device comprises a loading rod, a sealing ring, a substrate, a loading apparatus, and a self-centering apparatus. Through the changing of the positions of a rotating flange and an unbalance loading flange in the loading apparatus, the device achieves the adjustment of a three-dimensional vector force in different loading directions. The device achieves the self-centering force loading through a spherical positioning block and a conical positioning block in the self-centering apparatus, and effectively reduces loss caused by axis bending when the three-dimensional force is loaded. The substrate guarantees the flatness of the front and rear surfaces, prevents a force unbalance loading angle from being generated, and avoids the impact on the direction of the vector. The device achieves the loading of the vector force for the loading rod through hydraulic pressure, and a loading process is stable and high in precision. The device is simple in structure, is high in rigidity, is convenient for the flexible adjustment of the direction of the loading force, and achieves the loading of a big high-precision three-dimensional vector force.
