The provision of claimed diesel resource by means of self-diagnostic system application
Tractor is actively exploited in agriculture as well as in other spheres of life. Its operational time outcome leading to the necessity of major repair of both home and overseas samples may vary within rather wide time limits depending on exploitation facilities and some other factors. In this way the resource of tractor declared by the manufacturing plant is not always fully realized. The increase of faulty performance indicators to signal about the necessity of major repair of the agricultural machines in due time will permit the machinery to fulfil a considerable volume of work additionally. A self-diagnostic board system to discover faulty performance indicators has been developed by the author of the article. The system functions on the principles of homogenous programmable complexes to provide monitoring of tractors and to prevent performance failures of various groups of complexity. Tractors T-150K and Belarus-1221 were taken as objects of research. The author worked out the structure of self-diagnostic board system which suggests various possibilities of its implementation depending on the model and type of tractor. The author also determines the principles and algorithms which provide the effectiveness of the self-diagnostic system and exclude possible losses of information within the system. The reliability indicators of the tractors under research are compared and they show the level of self-diagnostic board system effect on degree of reliability of tractor for agricultural purposes. The research made shows that the total number of performance failures of Belarus-1221 is 16% lower in comparison with T-150K, while the indicators of an average number of failures per unit are lowered at 25%. Average parameter indicators of a flow of failures together with an average performance outcome in case of failure during the entire testing period are 18% with Belarus-1221; the probability of no-failure operation of Belarus-1221 is 1,6% higher if compared to T-150K.
