Installation and use method of vibration excitation device

The invention discloses an installation and use method of a vibration excitation device, and the method comprises the following steps: 1, designing the sizes of a cross brace and a telescopic supporting rod according to the size of a test model and a point needing vibration excitation; according to the magnitude of exciting force energy required by the test, the sizes of the corresponding connecting rope and the exciting block are selected; 2, oil is applied to the penetrating hole, it is guaranteed that the contact face between the penetrating hole and the connecting rope is smooth, and a vibration excitation device is assembled; and 3, according to the magnitude J of the mechanical energy, the included angle theta = 2arcsin [J/(ML)] of the vibration excitation block relative to the vibration excitation block when the vibration excitation block is vertically placed is calculated, the coordinate point of the vibration excitation block on the horizontal plane is found through the laser level gauge, the release
