| Abstract: | This paper transforms the dynamics equation of vibration system with finite degrees of freedom into its state equation and transfer function.We can analyze and simulate the vibration system in time domain and frequency domain by the state variable analysis method and the mechanical impedance analysis method in stead of the vibration mode analysis method using directly MATLAB simulation function and MATLAB control system toolbox function.This method can be explained by some examples.Thus,it can serve as a method in the vibration system's analysis and design. |
