复合材料层合圆柱壳中振动功率流特性
Characteristics of the vibration power flow in a laminated composite cylindrical shell
摘要
Abstract
Based on the Love theory, the internal forces and moments of laminated composite cylindrical shells are obtained from the relationship of infinitesimal stress-strain, and thereby the kinematic differential equation is derived. The characteristics of vibrationa power flow in a laminated composite cylindric shell were studied in the present paper. The vibration power flow from exciting force traveling along the shell was analyzed. It was concluded that all kinds of power flow transformed with each other during their traveling period, and ultimately tended towards a certain value. The vibration power flow carried by different internal forces was given to prove the characteristics of wave propagation while taking energy into consideration. The ratio of different kinds of waves can be determined quantitively according to the proportion of the power flow from different internal forces.关键词
