One of the most informative parameters that can be used to assess the current technical condition of mechanical systems is vibration. Vibrodiagnostic is carried out on the working equipment, without disturbance of a production cycle. This is important for systems that operate in a continuous mode where the stop for diagnostics is technologically and economically unjustified. Vibrodiagnostic measures significantly reduce the likelihood of an emergency situation at the facilities, and their repair is carried out only when and where it is really necessary. Nowadays, vibrodiagnostic, especially data analysis, is carried out mainly through the use of appropriate software. Modern software requires complex software implementation of certain techniques and algorithms for vibrodiagnostic, as their imperfection requires the participation of the operator in the analysis of diagnostic information. In vibration diagnostics, various methods of destruction of mechanical systems can be divided into two broad categories. The first category can be called the failure of the first pass, because the failure is expected for the first time when the voltage or shift exceeds a critical level. The occurrence of failure is usually associated with the occurrence of large stresses or shifts in the parts and elements of the mechanisms, so stochastic analysis of failure requires the study of extreme values \u200b\u200bof the process. Two different types of extreme manifestations are relevant. Fragile fracture and deformation (bending) are two types of destruction that can be classified in this category. Another broad category of failures is fatigue, in which failure occurs due to the accumulation of damage. The purpose of this paper is to analyze and model the probability distribution of vibration signal peaks as a criterion for estimating the probability of failure of any type when the dynamic response of the system is a random process.
