Savchenko V. Maintenance of reliability of agricultural machines and technological complexes.

The object of research is creation process of effectively going agricultural technological complex. The goal of research is maintenance of reliability of agricultural technological complexes and their components. Research Methods and apparatus is the methods of probability analysis, the methods of statistic analysis. Methods of statistic design attached to elaboration of new analysis methods and reliability parameters computation. Theoretical and practical results: worked up a reliability indexes computation method of type technological complexes, attached to use of loaded and unloaded reserve of production powers; estimation method of statistic resources, distribution descriptions on tests results, construction method of statistic resources model attached to parametrical refusals, and also want determination method in spare parts, permissive to make expense dynamics estimation of spare parts in dependence on periodicity of repair influences and from "age" of machine. The novelty of the innovations: in troduced notion of psevdoparallel elements junction in multimachinary systems and offered proper computation method; are worked up the specified machines reliability indexes estimation methods on results of brief tests and in case of parametrical refusals; is offered a want estimation method in spare parts. The degree of implementation - the reliability parameters and want level in spare parts handed over on enterprises-manufacturers, the recommendations on guaranteeing of reliability of technological complex inculcated in KSP "Berezivka" Kharkiv region. The domain of use - enterprises, related to making, exploitation and repair of agricultural technique; organizations, which plan elaboration, making and sale of spare parts.
