风电螺栓紧固力超声波测量的现状与展望OA

As a high-precision nondestructive testing technology,ultrasonic time measuring method is widely used in the field of wind power bolt fastening force testing.In order to further promote development and industrial application of ultrasonic time measuring method,the paper systematically summarizes the research methods,research results and existing problems of ultrasonic time measuring method in bolt fastening force measurement at home and abroad.In this paper we review the application value and research status of ultrasonic time measuring method for bolt fastening force of wind power,expound the necessity of bolt tension measurement of wind power units,and demonstrate the feasibility of ultrasonic time measuring method.The ultrasonic time measuring method is systematically summarize focusing on the classification,principles and experimental methods.This paper presents an investigation of the general formula principles,as well as various experimental methods.Combined with examples,this article shows that there remain issuses,challenges and prospects of ultrasonic time measuring method in the field of wind power bolt fastening force detection from the aspects of theory and practice.
