Abstract

See full text

A vibration excitation device comprises an input shaft, eccentric blocks and eccentric torque output shafts. The input shaft can drive the eccentric torque output shafts to rotate, and the eccentric blocks sleeve the outer sides of the eccentric torque output shafts. The eccentric blocks on the eccentric torque output shafts synchronously rotate along with rotation of the eccentric torque output shafts and generate a centrifugal force. The centrifugal forces of the eccentric blocks on one pair of exactly opposite eccentric torque output shafts are equal in magnitude and opposite in direction, but each pair of centrifugal forces forms a force couple. The magnitude and direction of the torque of each force couple periodically change based on the sine function rule over time, and under the action of the torques of the two pairs of force couples, the vibration excitation device generates an arc vibration in a horizontal direction.
