Problems solved by technology

However, the ultrasonic c-scan images are generally blurred and the lateral resolution is low. In order to make the measurement results more accurate, the scanned images must be processed, but the current data processing methods are not ideal.
At the same time, due to the existence of bolts in the bolt joint surface, the ultrasonic c-scan image is discontinuous, which affects the subsequent image processing
Moreover, when using a water-im

Abstract

The invention discloses a bolt faying face supersonic wave detection apparatus and a data processing method thereof. The apparatus comprises a mobile platform which is composed of a mobile support and a micro-motion measuring mechanism, and is suitable for measurement of any large-scale bolt faying face. An accurate angular displacement bench in the mobile platform can adjust an angle of an ultrasonic transducer accurately, and detection precision and efficiency are raised. According to the data processing method, a problem of image processing difficulty caused by a measuring result when detecting the bolt faying face is overcome, and a problem of an unsatisfactory image restoration result by employing a traditional Wiener filtering method is solved. According to the method, lateral resolution of an ultrasonic c scanning image is greatly raised.

Description

technical field [0001] The invention relates to the field of direct detection of properties of bolt joint surfaces, in particular to a method for ultrasonically testing the performance of bolt joint surfaces and an ultrasonic testing device using the method. Background technique [0002] The performance of the bolt joint surface directly determines the performance of the mechanical system, especially the more important bolt joint surface, such as knowing the bolt joint of the guide rail, will have a direct impact on the accuracy and accuracy retention of precision machinery such as machine tools. Therefore, it is very important to directly detect the properties of the joint surface, including the contact area, contact stiffness, and contact pressure of the joint surface. In actual production, the coloring method, film method, etc. are generally used to detect the joint surface, but these methods are to add some kind of measuring medium in the middle of the joint surface to m...
