Bowl-shaped ultrasonic array detection method for spherical rolling body of aviation bearing

The invention discloses a bowl-shaped ultrasonic array detection method for a spherical rolling body of an aircraft bearing. A special bowl-shaped ultrasonic array detection system for the spherical rolling body of the aircraft bearing is used. The aviation bearing spherical rolling body bowl-shaped ultrasonic array detection method comprises the following steps and contents in sequence: step 1, selecting a probe and determining sound field parameters; 2, determining a detection sensitivity parameter; 3, determining the space detection position of the rolling body; 4, planning a motion path of the rolling body; and step 5, detection implementation and result judgment. The invention provides a bowl-shaped ultrasonic array detection method for effectively detecting metallurgical defects in the rolling body, the detection sensitivity can meet the requirements of the strictest aviation detection standard, and the detection method is combined with the current eddy current and magnetic powder, so that the omnibeari
