Abstract
The article deals with the issues of choosing a redundancy method and the frequency of replacing tractor elements while ensuring the level of operational reliability in agricultural enterprises. It is noted that the operability of the system is ensured as long as there are reserve elements available to replace the failed main elements (and there is a possibility of switching the reserve elements into an operational state). One of the general methods for solving this problem is a method based on the use of Markov processes. In this case, the process of changing the states of the tractor is presented as a dynamic system, the state of which changes discretely in continuous time in a random manner.
Highlights
In the process of their intended use, tractors and their elements under the influence of external and internal factors lose their efficiency and consumer qualities [1,2,3,4,5]
The tractor's adaptability to carry out the specified types of work, as well as to work on refueling, preparation for use, storage and other operations performed during tractor operation, comes to the fore [2, 8]
The minimum sample size was set depending on the type and functional purpose of parts using the provisions of GOST 27.502-83
Summary
In the process of their intended use, tractors and their elements under the influence of external and internal factors lose their efficiency and consumer qualities [1,2,3,4,5]. It is possible to find and give an opinion on it only after partial disassembly In both cases, the restoration of the machine's performance is carried out by replacing individual faulty or worn out units and assemblies with repaired or new ones from the number of spare parts or the stock of exchange units [1, 1015]. The most typical maintenance tasks are performed when replacing non-recoverable elements – air and fuel filters, technical fluids at the end of the established resource. As a rule, these types of consumables are always in the field of view of service departments. It is advisable to use redundancy [9]
