The invention discloses a six-degree-of-freedom series-parallel electromagnetic vibration test stand, which comprises a support seat, a three-degree-of-freedom flexible support, an X-direction excitation device, a Y-direction excitation device, a Z-direction excitation device, a parallel linkage platform, a rotating device, a test workbench and a controller. The X-direction excitation device and the Y-direction excitation device are respectively used for generating reciprocating vibration in the X direction and the Y direction; the Z-direction excitation device can generate Z-direction reciprocating vibration and reciprocating swing around axes parallel to the X direction and the Y direction; the rotating device is used for driving the test workbench to generate rotating or centrifugal movement. The test stand can achieve vibration with six degrees of freedom at most, not only has multiple vibration degrees of freedom, independent and adjustable vibration degrees of freedom, but also has high vibration test load, low energy consumption and low equipment gravity center, can meet the requirements of more vibration test work, and has high vibration frequency and compact structure, thetest stand has the advantages of small occupied space, low production cost, high safety, simple and convenient operation and maintenance and the like.
