Análisis de los principales indicadores de fiabilidad de las cosechadoras de arroz New Holland l520.

The present work was carried out in the Rice Enterprise ‘Los Palacios’ during the rice crop season 2001–2002, with the objective of determining the main indexes of the croppers' of rice reliability New Holland L 520 under conditions of exploitation. By means of the employment of a methodology statistical-mathematician experimental probability was calculated (Pi), the half value (t) of the index of the reliability and the quadratic half deviation (σ). The determination of these parameters is carried out for the first time for these machines under the conditions of Cuba. The results of the researches will allow to determine the real necessities in spare parts and to take the measures to elevate the level of reliability of those combined. [ABSTRACT FROM AUTHOR]
