Finite element stress analysis of a combined stacker-reclaimer machine: A design audit report
share
Design audit or design verification is an important step in engineering of heavy mobile materials handling equipment. Usually, the costumers employ third parties for audition of contractors engineering. Here a part of design audit of a combined stacker-reclaimer machine is reported. This equipment is designed and constructed by a local supplier in Iran for the iron ore pelletizing plants at GOHARZAMIN Iron Ore Company. The structure plays an important role in mobile material handling machines such as Stackers and Reclaimers and its failure and damage may cause considerable financial and human life losses. In this report the undercarriage of stacker-reclaimer machine including gantry and traveling system are numerically analyzed. The Finite Element Method is used for stress prediction under the critical operating loads according to the design standards. The critical areas of the undercarriage are identified and it is observed that, the maximum stress is in the safe range.
