Hydraulic servo control seismic wave generating device and working method thereof

The invention relates to a hydraulic servo control seismic wave generating device and a working method thereof. The hydraulic servo control seismic wave generating device includes a transverse wave generating device and a longitudinal wave generating device. Shock absorption airbags and a transverse wave actuator which is arranged on a bracket are arranged between the ground contact plate and pressure bearing plate of the transverse wave generating device; a displacement sensor is built in the transverse wave actuator; one end of the transverse wave actuator is provided with a pressure sensor;the ground contact plate is provided with a bracket; and a guide rail is fixed on the bracket. A longitudinal wave actuator is arranged between the ground contact plate and pressure bearing plate ofthe longitudinal wave generating device; a displacement sensor is built in the longitudinal wave actuator; one end of the longitudinal wave actuator is provided with a pressure sensor; the pressure bearing plate is fixed on a
