MODELS OF RELIABILITY OF MULTI-PURPOSE MACHINES IN A HISTORICAL PERSPECTIVE
Journal Title: Topics in Intelligent Computing and Industry Design (ICID) - Year 2017, Vol 1, Issue 2
Abstract
The basic function characteristic of the reliability of the multi-purpose machines is the mathematic model describing the characteristics of the time of the correct functioning. The subjects of the research were the wheat harvesters produced nowadays, and the harvesters produced in the 80’s. During the research, the time of the correct functioning has been registered along with the time of repair in the agrotechnological season and the potential cause of the break has been identified. Whilst selecting the mathematic models for the reliability of the machines produced in specific times of exploitation, the analysis of damage causes has been created. Based on the results, the conclusion was that the model of the reliability of wheat harvesters produced nowadays is the exponential function. In the process of exploitation, the damages had the saltatory character not dependent on the using process. The basic cause of the damage were the operator’s errors and the hard conditions of exploitation (69%). When it comes to the harvesters researched at the earlier time, the reliability is best described by logarithmic and Weibull’s functions. It shows that they have more complex damage causes which were usually due to the overuse of parts.
