High-precision modal parameters identification method and modal experiment of roof bolter＇ s drilling arm
Abstract：A novel method was proposed to identify the modal parameters of roof bolter＇ s drilling arm with high preci- sion. In order to verify this method, we made an experiment, and the results showed that the method had a good validity and reliability. The proposed method is less affected by mode superposition and can overcome the disadvantages of tra- ditional modal parameters identification method. Furthermore, the method can help to update the FEM model of roof bolter＇ s drilling arm and the identified modal parameters also provide basic data to further dynamic analysis and opti- mum design.
