Abstract
The article presents the results of research in the field of ensuring the performance of complex technical objects on the example of transport and technological machines (TTM), which include transport equipment, as well as technological machines (excavators, loaders and other equipment that performs a technological process). The strategy of forming a system of maintenance and repairs taking into account the technical condition of TTM elements is described. The strategy provides for the division of structural elements of machines into four groups, depending on the principle approach to calculating the frequency of their repair. The criterion for determining the frequency of repairs is the probability of reaching the maximum values of characteristics during the inter-repair period, as well as the degree of criticality of the consequences of possible failure of the element.
Highlights
The efficiency of transport and technological machines (TTMs), as well as of any material object, is determined by the level of their reliability, which is defined as a property to maintain for a set period of time a certain range of the values of all parameters that characterize the ability to function in the set modes and application conditions [GOST 27.002-83]
The subject of the research is a TTM as a complex technical system that consists of components, the frequency of replacement of which determines the reliability of the whole machine
The impact of the amount of possible damage from a sudden failure on choosing the frequency of repairs of machine components has been described
Summary
The efficiency of transport and technological machines (TTMs), as well as of any material object, is determined by the level of their reliability, which is defined as a property to maintain for a set period of time a certain range of the values of all parameters that characterize the ability to function in the set modes and application conditions [GOST 27.002-83]. The term “operability” is of similar meaning. It is defined as the condition of an object upon which it is capable of its intended functions while maintaining the values of operating (set) parameters within the range established by the regulatory documents. The parameters, that characterize functioning, determine the performance figures of a machine, i.e. its performance efficiency, load capacity, power capacity, propulsion performance, speed performance, and braking performance, motor burn process parameters, etc. From the consumer’s point of view, the term “operability” is more understandable, with its parameters being obvious and measurable
