A six-degree-of-freedom series-parallel electromagnetic vibration test stand, comprising a support base (1), a three-degree-of-freedom flexible support (2), an X-direction excitation device (3), a Y-direction excitation device (4), a Z-direction excitation device (5), a parallel linkage platform (6), a rotating device (7), a test workbench (8), and a controller (9). The X-direction excitation device (4) and the Y-direction excitation device (5) are configured to generate reciprocating vibration in an X direction and a Y direction, respectively; the Z-direction excitation device (5) can generate Z-direction reciprocating vibration and reciprocating swing around axes parallel to the X direction and the Y direction; the rotating device (7) is configured to drive the test workbench (8) to generate rotating or centrifugal movement. The test stand can achieve six degrees of freedom of vibration at most which are independent and adjustable, and has vibration test load, and low energy consumption and low equipment gravity center, thereby meeting requirements of more vibration test work.
