摘要： A vibrating apparatus for vibrating a mold 1 by an electrohydraulic stepping cylinder 5 through a link mechanism 3 is characterized in that when a driving signal delivered into a drive unit 26 for the stepping cylinder 5, the actual acceleration of the mold 1 is fed back to a target waveform signal for the mold 1 and compensating signals for cancelling the operation delay of the stepping cylinder 5 and the signal transfer lag due to elastic deformation of the link mechanism and the like are added thereto to make feed-forward compensation.
