Abstract

A theoretical study of the pulse frequency of acoustic emission as a function of sliding speed and load in the friction units of hydraulic drive forest machines has been conducted. It is shown that an increase of the sliding speed of friction units has allowed to increase in direct proportion the pulse frequency of acoustic emission. With increasing load in the friction units the pulse frequency initially increases rapidly and then comes a point of saturation of silnal.
