description The invention relates to a device for testing rock core permeability under the function of a stress wave pulse. The device includes a high-pressure gas source, a rock core clamp and a gas flowmeter. Adownstream pipeline of the high-pressure gas source communicates with an inlet of the rock core clamp, and the gas flowmeter communicates with the outlet of the rock core clamp. The device also includes an excitation circuit, a stress wave generator, a stress wave amplifier, a waveguide and a confining pressure pump. The stress wave generator is at the inlet end of the rock core clamp, and is connected to the axial end surface of a rock core through the stress wave amplifier and the waveguide. The confining pressure pump communicates with the rock core clamp. The device and a testing method achieve rapid measurement of rock core permeability under the function of a stress wave pulse, can stimulate rock core permeability changing characteristics under different stress wave pulse frequencies and loads, and achieve
