Methods for calculating vibration power flow

Wu Xianjun1, Zhu Shijian2 (1.School of Mechanical and Electronic Engineering, Wuhan University of Technology, Wuhan 430070, China; 2.Institute of Vibration & Noise, Naval University of Engineering, Wuhan 430033, China)  
Vibration power flow method is the dominant analysis method for the vibration of flexible structure. In the power flow analysis the key problem is how to calculate the vibration power flow. The mobility-based method was traditionally used in vibration power flow calculation. But both its precision and suitability for complicated structure are not very good. Two other methods, which are the vibration power flow calculation method based on wave analysis and the vibration power flow calculation method based on finite element analysis, were presented in this paper. A calculation example was given. Results prove that the precision of the traveling wave method is very high, and the precision of the finite element method is good if the element is small enough. The finite element method is applicable to complex structure, so it has great application value in engineering.
