Dynamic Load Identification of Cutting Arm of Roadheader

In order to research internal statistics rule of roadheader,carried through test and analysis when EBZ260TY type roadheader cut artificial rock.Load stress of starboard and upside of cutting arm on roadheader were identified by workout theory of one dimensional load spectrum,and truly obtain variational rule of cutting arm load on roadheader.It is helpful importance to structure improvement and optimization of roadheader.
