Type: article
Abstract: • Variable loads play and important role in the design of substructure components of mining and material handling machines • .The undercarriage components of rail machines are exposed to fatigue caused by the superstructure slewing and luffing • The undercarriage components of crawler machines are prone to fatigue due to loads resulting from mining and travelling The article presents the current progress of research and development in of mining and material handling machines and focuses on estimation of the actual loads acting on the discussed objects, especially in the area of their undercarriage. In many cases, the standards currently used miss the case of verification fatigue scenario, or the values adopted are much lower than those observed during operation. The following paper briefly describes the possible consequences of failure in the machines described in article, the current approach of standards to fatigue, and the current progress of research and development in the context of fatigue calculations with respect to the alternating loads acting on the undercarriage. The described research will allow in the future to update the existing calculation standards or propose additional activities during the design of mining and material handling mega machines. This will allow for better optimization of the structure in terms of its resistance to fatigue damage.
