Abstract: Provided is a six-degree-of-freedom vibrational excitation foundation platform, which solves the problem of the existing vibrational excitation foundation equipment that a vibrational excitation frequency band is narrow due to low natural frequency of the equipment. The six-degree-of-freedom vibrational excitation foundation platform includes a marble platform support frame, which is fixedly installed on a concrete floor through a backing plate; and a marble platform, which serves as an excitated device and is located in a middle of the support frame, and four sides of the marble platform support frame are connected to the motors fixedly connected to the support frame through connecting plates. The parallel connection of motor outputs solves the problem of insufficient excitation, and natural frequency of each part of the platform is increased by optimizing the marble platform and the support frame, such that the frequencies are controllable within the vibrational excitation frequency band.
