摘要
针对加肋圆柱壳结构提出了一种功率流测试方法。基于Flugge的圆柱壳理论和功率流定义推导了加肋圆柱壳轴向波和弯曲波功率流测量公式,实现了通过加速度和应变信号获取功率流信息。以加肋圆柱壳有限元模型为对象,施加轴向激振力和横向激振力,提取加速度信息和应变信息并利用本文方法计算功率流,与利用功率流定义式的计算结果基本一致,验证了本文方法的正确性。
A power flow testing approach is presented for ring-stiffened cylindrical shell in this paper. According to Flugge cylindrical shell theory, the power flow testing equations are derived to obtain the power flow information from the acceleration and strain signal. In order to verify the presented approach, the finite element model of the ring-stiffened cylindrical shell is excited by axial and lateral force, and the computed acceleration and strain signal is used to obtain the power flow by the presented approach, which is consistent to the computed result by the definition of power flow.
