Summary:The invention relates to an ultrasonic transducer load equivalent model modeling method. The method comprises the following steps: S1, constructing an electromechanical equivalent model of the ultrasonic transducer based on an equivalent circuit theory; s2, inputting the electromechanical equivalent model of the ultrasonic transducer into an MATLAB simulation environment; s3, determining the input impedance characteristics of the ultrasonic transducer under the pressure load through a comparison method; s4, on the basis of the determined input impedance characteristics, matching the optimal impedance under the pressure load through a cross value mapping method; and S5, performing curve fitting on the pressure load applied to the ultrasonic transducer and the optimal impedance by using a least square method. According to the method, the corresponding optimal impedance under the dynamic pressure load is found through the cross value mapping method, and the series of data are fitted through the least square meth
