Energy Absorption Numerical Analysis of Mine Impingement Thin-Walled Components with Different Configurations

Abstract:

For the effective prevention and control of mine bumps, or to a certain extent, to reduce the loss the losses caused by impact ground pressure accident,thin-walled components are proposed to be applied as a scaffold components in roadway supporting. Components impingement is reflected in the component crushed process ,in which the impacting energy absorption and crushing space provide certain amount of energy to free up space. The energy absorption characteristics of different configuration thin-walled components has been simulated with ABAQUS finite element, such as the conventional square,regular hexagon, round and origami square, regular hexagon etc,.and the results showed that: (1) The problem of conventional components is larger load fluctuation coefficient. Origami component is a kind of perfect impingement components ,as it can reduce peak loads and the load fluctuation coefficient effectively. (2) Under different ratios width-to-thickness, components can have different deformation modes, but the relationship of peak load and wall thickness is near linear and has nothing to do with the deformation modes. (3) The component can have a relatively lower crushing peak load and load fluctuation coefficient and relatively higher specific energy absorption,if given a suitable diamond concave angle. impingement components using combined with existing supports can make the existing supports to become top beam impingement support , mudsill impingement support ,two sides impingement support and impingement hydraumatic support and so on.
