The invention discloses a rock damage test experiment table under ultrasonic vibration. The experiment table comprises a guide fixing mechanism, a rock clamping mechanism, a hydraulic pressurization mechanism, an ultrasonic vibration mechanism, a rock amplitude measurement system, a sound emission measurement system and an infrared feature measurement system. According to the rock damage test experiment table under the ultrasonic vibration built by utilizing an amplitude detection technology, a sound emission technology and an infrared detection technology, dynamic testing of rock internal crack development, rock internal stress change, an attenuation condition of a stress wave in a rock and effective rock crushing depth can be realized; and the damage process of the rock under the ultrasonic vibration can be comprehensively tested in multiple aspects, and optimal rock crushing parameters under the ultrasonic action, including a frequency, a static pressure, an amplitude and the like are determined, so that the defects and the errors of a single detection method are reduced, the experiment efficiency is improved, favorable support is provided for the research of an ultrasonic rockcrushing mechanism, and the experiment table has the advantages of being accurate, convenient and economical.
