| Evaluation of maintenance strategies is an issue which must widely be considered. This paper describes failure rate, mean time between failures (MTBF) and availability analysis for Austoft 7000 sugarcane harvesters series used in agro-industries in southwestern Iran. Sugarcane harvester was divided into three subsystems and the failures were studied for 1800 working hours. The failure rate of subsystems including hydraulic, mechanical and electrical were calculated 0.087, 0.052 and 0.012 h-1, respectively and the total failure rate was 0.15 h-1. MTBF after 1800 working hours were obtained 11.46 h, 19.35 h and 85.71 h for the aforementioned subsystems and machine MTBF was 6.64 h. Among the three studied subsystems, hydraulic with maximum failure rate and... |

| the performance of agricultural machines depends on the reliability of the machinery used, the operating environment, the maintenance efficiency, the operating process, the technical expertise of the farmers and etc. As the size and complexity of farm equipment continue to increase, the implications of equipment failure become over more critical. Therefore, reliability analysis is required to identify the bottlenecks in the system and to find the components or subsystems with low reliability for a given designed performance. It is important to select a suitable method for data collection as well as for reliability analysis. This paper presents a case study describing reliability and availability analysis of the sugarcane 7000 series chopper harvester at... |
