Machinery & Energetics

The article develops a scientific approach that includes a system of interrelated methods in conjunction to objective substantiation of rational values of the turnaround standards of agricultural machinery from the position of uniform methodological principles in the conditions of market relations and growth of competition in the sector of agricultural engineering. The method of calculation of the indicator "probability of failure" and justification of the turnaround standards of cars based on it that includes the possibility of selecting the rational values of consumer risk and supplier in the definition of acceptable from the point of view of security of the turnaround standards of the machines. The proposed method of calculating the indicator "average time to failure" and the definition of rational values of the overhaul of standards, taking into account the combined criterion (achievements / calendar time) setting of the machines in repair. According to this method, anindependent establishment of rational values of operation time and lifetime of the machines in the run time
