Zusammenfassung: | Ensuring the safe operation of complex technical systems is an urgent task. Complex technical systems include lifting, mobile, agricultural machinery, etc. Absolutely every complex system fails during operation. At the same time, failures can have different effects not only on reliability indicators, but also on the degree of safety. The degree of safety of operation of complex equipment is directly influenced by the probability and nature of the occurrence of failures. Thus, in order to increase operational safety, it is necessary to reduce the risk of a negative event, which is defined as the possibility of an adverse event occurring, that is, a combination of the degree of negative consequences with the possibility of its occurrence. The article provides an example of calculating the risk of failure; a method for calculating the parameters of the three-parameter Weibull distribution is proposed; an algorithm for determining three parameters of the Weibull law for a sample is given; the results of parameter calculations are presented; Proposals have been put forward for ways to increase the level of reliability and safety, respectively. |
