Modal Analysis of Eccentric rotor for Multi-layer leather High-speed Cutting Machine based on Bond Graph Method
The stability problem of eccentric rotor in high-speed cutting process is the main factor affecting the performance of cutter transmission system.A modal analysis of eccentric rotor for multi-layer leather high-speed cutting machine based on bond graph method is proposed to obtain the complete modal parameters.The lateral vibration mathematical model of the eccentric rotor is build using bond graph theory.The inherent frequency,deformation modal vibration shape,and velocity modal vibration shape of eccentric rotor are obtained through the Matlab numerical calculation.Then the modal test for eccentric rotor is done and the compared results are given.The results show that using the bond graph method solves the problem more easily than Newtons theory,obtains the two type of modal vibration shape,and its relative error is less than 0.4%.The complete modal information is given that provides a theoretical basis to better understanding the dynamic properties of eccentric rotor and provides the basic parameters for dynamic performance optimization and dynamic balancing analysis of cutter transmission system.
