附加质量对自由边板振动影响研究
Research on the influence of additional mass on the vibration of free edge plates
摘要
Abstract
The equipment placed on the rectangular plate may change the vibration characteristics of the rectangular plate.The free vibration characteristics of a rectangular plate with concentrated mass opposite side free opposite side simply supported are solved by different methods.According to the vector and streamline diagrams of power flow,the influence of different mass distributions on the propagation characteristics of power flow in the plate is analyzed.The effect of the lumped mass on the vibration wavenumber is studied by frequency wavenumber spectrum analysis.Our results show the concentrated mass makes the vibration power flow concentrate and form vortex,and the reduction of the interval of the concentrated mass reduces the amplitude of the vibration response of the rectangular plate.关键词
