| Abstract: | In this paper,the common simulation methods of mechanical systems and their shortages are discussed. A new method for the dynamics digital simulation of mechanical systems based on Simulink is presented. A mechanical vibration system which has a dynamical absorber is taken as an example to describe the particular process of the dynamical simulation. The mathematical model and digital simulation model in Simulink are established successively. After the setting of all simulation parameters,the simulation is carried out,then the reliability of the obtained simulation results are analyzed,which shows that the method is more exact and efficient. |
