An application method of a large mobile container-type residual stress control device, using the mobile residual stress control device according to claims 1-9, characterized in that: The following steps are involved: A plurality of multi-layer racks are installed in the equipment room, and a plurality of ultrasonic power supplies are placed on the racks; According to the size of the component to be regulated, the distance between the two support frames is adjusted, and after the distance between the two support frames is adjusted, the component to be regulated is placed on the placement frame; Then, the protective cover is laid on the connecting rod to prevent foreign matter from entering during the experiment; After the placement is completed, the pumping system starts to store water in the pool, and stops storing water when the water volume reaches the requirement; At this time, the ultrasonic power supply supplies power to the ultrasonic transducer, so that the plurality of ultrasonic transducers on the two support frames can perform contactless ultrasonic control on the component to be debugged; After the debugging is completed, the drainage system is powered to discharge the water in the pool; Finally, the component is taken out and the ultrasonic control is completed.
