Abstract

The invention provides a mechanical vibration platform with various vibration modes. The mechanical vibration platform comprises a platform top and a base. Four corners between the platform top and the base are each vertically and fixedly connected with a rubber spring. The mechanical vibration platform is further provided with four inertial vibration exciters fixedly connected with the platform top respectively. Each inertial vibration exciter is located in the center position between the two corresponding adjacent rubber springs. The positions where the four rubber springs are located form a square. The positions where the four inertial vibration exciters are located form a square as well. The projection of the center of the square formed by the four rubber springs and the projection of the center of the square formed by the four inertial vibration exciters are overlapped relative to the base. The mounting angle of each inertial vibration exciter relative to the platform top can be adjusted, and the mounting angles of every two inertial vibration exciters on the opposite angle positions of the square are completely the same. By adjusting the mounting angles, the platform top can vibrate in various modes such as linear vibration in the perpendicular surface, the horizontal surface and space and circular vibration so as to meet the requirements of different experiment objects.
