A Test device for verifying the simulation result of electromagnetic-ultrasonic structure parameter and energy conversion efficiency relates to a device for verifying the simulation result of electromagnetic-ultrasonic structure parameter and energy conversion efficiency. The device solves the problem of verifying the correctness of the simulation relation curve of electromagnetic-ultrasonic structure parameter and energy conversion efficiency. When in use, the relative position between a coil and a part to be tested is determined by adjusting a rotary table, then a fastening screw on an axlesleeve is used to fix the position of the rotary table so that the part to be tested can not perform relative motion, then a lead screw 1 is used to drive the entire device to move up and down along a guide rod so as to determine the initial displacement of a coil mounting rack and the part to be tested; and after the initial position is adjusted, the verifying test of lift distance and energy conversion efficiency can be performed. The invention is applicable to the simulations of verifying the simulation result of electromagnetic-ultrasonic structure parameter and energy conversion efficiency.
