Abstract
The reliability of forestry machinery is closely related to the labor intensity of its maintenance and repairs. Untimely diagnostics of failures entail additional financial losses due to machinery repairs and reduce the effectiveness of production. This paper describes a method for diagnosis of hydraulic drives of forest machinery in the process of their operation. A set of complementary methods relevant to the problem at hand was used to achieve the set goal, including analysis, abstract-logical, and analytical methods. The research generalizes the experience of Russian and foreign experts in the studied subject. In the course of experiments a lopping machine was tested. The developed technique is based on characteristics of the random process produced in the interaction of machine working parts with a tree. We obtained the normalized spectral density of loading the hydraulic drives of the tested lopping machine when processing trees under different operating time. By the rate of displacement of density peaks one can estimate the technical state of hydraulic drives. Thus, the use of the offered technique can increase the lifetime of machinery and reduce its wear.
Keywords: forestry machinery; wear; failure diagnostics; machine operation; hydraulic drives.
