Узагальнені результати досліджень з визначення впливу тривалості усунення технологічних відмов льонозбиральних комбайнів, що спричинені зупинками агрегату на очищення робочих органів комбайна від рослинних решток і тривалості виконання щозмінного технічного обслуговування льонозбиральних комбайнів на продуктивність комбайнового агрегату. З’ясовано закон розподілу наробітку на технологічну відмову і тривалості їх усунення та вплив числа технологічних відмов комбайна за годину змінного часу на продуктивність комбайнового агрегату. Обобщены результаты исследований по определению влияния продолжительности устранения технологических отказов льноуборочных комбайнов, вызванных остановками агрегата на очистку рабочих органов от растительных остатков, и продолжительности выполнения ежесменного технологического обслуживания льноуборочных комбайнов на производительность комбайнового агрегата. Определены закон распределения наработки на технологический отказ и продолжительности их устранения, а также влияние числа технологических отказов комбайна в час сменного времени на производительность комбайнового агрегата. The investigation is aimed at enhancing the efficiency of using flax harvesters which was assessed by means of the production capacity of machine units as components of these harvesters. The use of flax harvesters under real conditions of harvesting fiber flax is investigated. The author studies the duration of maintance in shifts and in the basic time of the shift, as well as the distribution of the operating time with respect to the technological failure and the duration of removing failures of flax harvesters. The author also determines the qualitative and quantitative relations between the quoted indices and suggests the model equations of regression which describe the revealed quantitative changes in these indices. The author determines the laws of distribution of the operating time before failures and the terms for removing them/ The paper specifies the number of technological failures of the harvester per hour of the shift of its operation. The paper analyzes the correlation between the production capacity and the coefficient of using the shift working hours of the flax harvester unit and the number of technological failures of the harvester per hour of the shift time. On the basis of the specified coefficient of the correlation and the correlation ratios with the use of the Student t-criterion the author determines the non-linearity of the correlation between the harvester unit production capacity per hour of the shift time and the terms for removing technological failures. Within the shift time and the part of this term in the structure of the shift time which are described with the equations of dipping hyperbolas. The changes in the investigated production capacity depend on the partial coefficient which takes into account the idle time of the harvesting unit due to the process of removing technological failures. The above changes also depend on the reliability coefficient of the technological process and can be described with the equations of the corresponding gradually ascending hyperbolas. The author reveals the curve linear correlation links between the production capacity of the harvester unit per hour of the shift time and the term of the shiftly technical maintenance of the flax of the flax harvester, the part of this term in the structure of the shift time, partial coefficients of using the time for the shiftly technical maintenance with respect to the duration of the shift and the level of providing shiftly technical maintenance. The corresponding correlation and regression models are determined as well.
