Technological machines, construction resources, efficiency and safety

Abstract

Abstract. Understanding the direct relationship of the person, his activities Wednesday habitats requires not only new methodological approaches to research, but, first and foremost, clarify the existing scientific theories, their coherence with the development the environment Wednesday. A model of modernization of transport and technological machines as a factor in the realization of tasks of improving their effectiveness, safety and environmental performance. The main focus in addressing modifications of technological machines in use is considered lowering their material intensity, by adopting a more rugged and durable in endurance and wear materials. Modified methodology of estimation of residual resource of technical facilities by implementing technology upgrades for further reliable and safe operation. In the method a key factor is the effective and safe operation. Developed a calculation model of optimization of the resource in terms of assessing risk of system failure due to functional aging; optimization model of the resource, frequency of maintenance and wear limit of units in terms of assessing risk of occurrence of a system failure affecting safety. The solution of the question of resource upgrading to provide manufacturers, as an additional stage of the life cycle of construction machinery and means of complex mechanization.

Triad model: simulation - functional tensometry - information database in the assessment of the reliability of technological machines

“…Obtaining information about the locations of the reparation points will additionally create a data bank on the amount of external and internal loads in all connections of the machine's systems and monitor its reliability throughout the life of the machine. When disposed of, this information will provide information about the residual resources of the elements for their reuse or the purposefulness of recovery, which in turn will ensure environmental friendliness and cost-effectiveness for machines owners [1,5].…”

“…As it is known, the unit is a complex technical system characterized by geometric, structural and functional parameters, the values of which were determined in the preoperational period, after commissioning, go into the category of partially determined in the presence of a built-in control and measuring apparatus for assessing the state or uncertain indicators, in case of their absence [1][2][3][4][5].…”
