Reliability Analysis of Forest Machines Due to FMEA Method

Abstract

The article deals with the research of operational reliability of forest felling machines with the method FMEA (Failure Mode and Effect Analysis) and its implementation for observed machines in the organization. Forwarders 810D by John Deere were chosen for this research. The research was realized in real operational conditions. Application of the FMEA method allows flexibility in case of unexpected situations and optimization of human potential abilities. FMEA tool is a tool preventing outages operational reliability and preventive tool for ensuring the maintenance of facilities. This paper explores and verifies the operational reliability theory in practical real-world conditions, resulting in a reduction in operating (variable) costs, minimization of failures and readiness and increased performance of observed machines.

FMEA method in operational reliability of forest harvesters

“…In the future with higher age of machines there is necessary to re-evaluate and set up shorter terms of operational maintenance for machines because it is defined by a curve of failures intensity. For easier diagnostics of individual elements in the system it is useful to implement new and modern methods of technical diagnostics [18].…”

“…It involves a logical diagram that shows the relation between the system components and their failures. [18] presented a review of the research performed on FTA with its advantages and shortcomings. Because FMEA is restricted to analyze only a single cause of an effect, FTA augments the feasibility of FMEA.…”

Lubricant Analysis as the Most Useful Tool in the Proactive Maintenance Philosophies of Machinery and its Components

“…However, careful inspection, assessment of the physicochemical properties of the oil refills and determination of the impurities and additives in the oil require some practical experience. Practical experience in oil analysis teaches us that the most successful programs are those that arise after careful evaluation and in conjunction with the objectives set [7,18,20]. The basis is to develop a quality concept at the outset so that it does not have to be modified later.…”
