- Abstract
This article discusses the acoustic method for diagnosing a non-breaking surface electrical contact made by a bolted connection. Selection of the acoustic method based on reduction of amplitude of an ultrasonic wave, passed through object of control which is the most effective for control of density of contact connection is carried out. Selection of the necessary equipment for monitoring procedure of density of non-demountable contact connection is executed. On the basis of the carried-out selection the experimental stand is created. Experimental data of an ultrasonic through sound passing of object of the control, density of contact showing influence on passing of an ultrasonic signal are obtained. Possibility of application of an acoustic method for control of density of the electric contact executed by connection by a bolt connection is proved
