![]() First, a simplified dynamic model of a typical blade disk rotor system is constructed by using the classical continuous parameter modeling method. The innovation of this paper is to reasonably explain why such response characteristics appear. ![]() Usually, the response characteristics can be obtained through numerical analysis, but we do not know why such characteristics appear, which hinders our understanding and utilization of vibration. These response characteristics can be used in many aspects, such as condition monitoring and fault diagnosis. The important role of a dynamic model is to study the response characteristics of a system under different parameters or fault states.
