The invention discloses a vortex flow transducer evaluation method based on fractal information dimensions and relates to an optimization algorithm of a stimulation curve in planar vortex flow transducer design. Information dimensions in a fractal geometry theory are adopted, finite element calculation is performed on vortex flow distribution produced on the perfect conductor surface by an exciting coil, information entropy, distributed in different directions, of virtual cracks at different scales in the strongest vortex flow position is obtained, and information dimensionality of the information entropy changing with virtual crack scale variation is obtained. The fractal information dimension is taken as an optimization method of a vortex flow transducer stimulation curve, and the changing speed of the intensity of the mutual action between vortex flow and cracks induced by the stimulation curve with reduction of crack lengths is evaluated.
