Title
(EN) THREAD FORMING FASTENERS FOR ULTRASONIC LOAD MEASUREMENT AND CONTROL
(FR) ORGANES DE FIXATION FORMANT LE FILET PERMETTANT DE MESURER ET DE COMMANDER LA CHARGE ULTRASONORE
Abstract
(EN)
An ultrasonic load measurement transducer (14) is mated with a thread-forming fastener (12) to provide a load indicating thread-forming fastener that can be used for the precise and reliable assembly of critical bolted joints, such as those in the automobile and aerospace industries, among others. Steps can then be taken to accurately measure and control the load in the thread-forming fastener during tightening, and to inspect the load in the thread-forming fastener after assembly. A similar result can be achieved for a thread-locking fastener by mating an ultrasonic transducer with the thread-locking fastener assembly.
(FR)
Un transducteur de mesure de la charge ultrasonore est accouplé avec un organe de fixation formant le filet afin d'obtenir un organe de fixation formant le filet indiquant la charge qui peut être utilisé pour l'assemblage précis et fiable de joints boulonnés critiques, tels que ceux utilisés notamment dans les industries automobile et aérospatiale. On peut réaliser une mesure et une commande précises de la charge subie par l'organe de fixation formant le filet pendant le serrage et une inspection de la charge subie par l'organe de fixation formant le filet après l'assemblage. Un résultat semblable peut être atteint pour un organe de fixation verrouillant le filet par l'accouplement d'un transducteur ultrasonore avec l'ensemble organe de fixation verrouillant le filet.
