The invention belongs to the technical field of automobile testing, and particularly relates to a five-freedom-degree automobile seat vibration test table capable of carrying out automobile seat smoothness tests and comfort subjective and objective evaluation tests. The test table comprises a machine body part A, a control system B and an upper computer C, wherein the control system B is connected with the machine body part A, the upper computer C is connected with the control system B, the machine body part A comprises a clamp module, a motive power module and a bottom support module, the motive power module is arranged under the clamp module, and the bottom support module is arranged under the motive power module. The five-freedom-degree automobile seat vibration test table provided by the invention is obviously superior to the existing single-freedom-degree seat test table in the aspects of precision, structure, installation, maintenance, environment pollution, noise and performance testing, the limitation of hydraulic motive power sources is overcome, in addition, the test table can be used for carrying out smoothness tests and comfort subjective and objective evaluation tests on an automobile seat, and the development time of the automobile seat is shortened.
