Lightweight Design for Coal Mine Rescue Robot’s Swing Arm Brackets

Abstract:

By analyzing the force of the Coal Mine Rescue Robots swing arm brackets, the maximum torques of the Coal Mine Rescue Robots swing arm brackets are calculated, the results are applied into finite element model, the maximum stress of brackets are much smaller than allowable stresses of the materials, so there is a large optimise space. Optimum design of Swing Arm Brackets are carried out by changing materials and dimensions. After simulating analysis, it can be seen that the lightweight design for out-bracket have better effect through cutting out materials rather than changing its materials. The results of this optimization may conserve materials and reduce energy consumption. And it has significant in successfully applying the robot into the coal mine underground after disasters and improving the using time of the batteries.
