AI Technical Summary
In existing technologies, methods for detecting foreign objects in enclosed areas of aircraft structures are inefficient, susceptible to human factors, have a high probability of missed detections, and pose safety risks.
A vibration test bench is used to apply continuous vibration force to the product under test. Sound signal acquisition sensors are used to collect the collision sound signals of objects inside the closed area, and the results are analyzed and processed by a comprehensive test bench to determine whether there are any foreign objects.
It has automated and digitized the detection of foreign objects in the enclosed areas of aircraft components, improved the detection accuracy, and reduced safety and quality risks.
