Abstract

The article discusses the method of preliminary analysis of the reliability of the design of peat machines (PM) at the design stage. For the designed TM, it is possible to assess the reliability using generalized statistical data on similar peat machines, but significant errors arise that do not allow predicting the technical condition of the equipment under development with the required accuracy. The proposed technique makes it possible to evaluate the developed design of the machine in terms of reliability based on the analysis of the operation of similar units of existing PM. For this, the existing peats machines are divided into separate mechanisms, for which there are statistics on failure parameters. The division of the designed machines is carried out in a similar way; while in order to obtain the necessary reliability parameters, it is proposed to use the coefficient calculation method, taking into account the presence in the developed PM design of the number of the most critical parts and assemblies. Thus, the use of data from the operation of existing PM makes it possible to improve the quality of predicting changes in the reliability parameters of the machines being developed, and as a result, during their operation, a decrease in the number of downtime due to difficult-to-predict failures is achieved, which makes it possible to increase the seasonal productivity of PM.
