摘要:
Flow-induced vibration and stabilities of the parallel-plate assemblies are studied theoretically. A model of multi-parallel-beams joined with single-beam is adopted in the theoretical analysis of the natural vibration characteristics of the parallel-plate assemblies. The functions of the dry-modal mode are used as trial functions to solve the equations of the complex-modal mode by the variational method for the natural frequencies and modes of the wet modal. The critical flow velocity and destabilizing deflection are solved by the direct method and the variational method for the stability of ...
