| description | In view of problem that it is difficult to get dynamic load of working face equipments in coal mine underground, the paper proposed a load identification method of roadheader based on vibration acceleration signal and stress signal, introduced basic principle and implementing steps of the method. It took false rock wall cutting by EBZ260 roadheader on the ground as experiment object, selected data within 11 s from cutting to stopping of the roadheader to make analysis which can get corresponding relation between average energy of vibration acceleration and average stress, then used the least square method to get fitting curve between average energy of vibration acceleration and average stress, so as to get function expression between average energy of vibration acceleration and average stress through the fitting curve. The method provides a new way for indirect measurement of dynamic load of roadheader through vibration acceleration. |
