Abstract

A novel method was proposed to identify the modal parameters of roof bolter's drilling arm with high precision. 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 traditional 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 optimum design.
