A Steel Headframe Structure before and after the Comparison and Analysis of the Performance of Process Modification
Abstract:
Because the coal mine derrick technology needs, to be in from the original winch system of backward 10m based on a new set of new ground winch system, resulting in the original derrick structure stress state change. By using SAP2000 finite element software, the establishment of three-dimensional finite element model, the dynamic characteristics and technological transformation and bar stress were analyzed, for the coal mine derrick technological transformation to provide certain reference.
