The equations of motion are derived from the extended Hamilton’s principle for dissipative systems, where the fluid–structure interactions are represented by a wake-oscillator type phenomenological model. Bending, twisting, and axial d

Seishi Ogawa,Yasuhito Nanya,Go Yamamotocoupling dynamic model is developed. A nonlinear differential pressure model at valve port is applied to model the axial vibration of fluid, and a nonlinear wake oscillator model is used to excite the valve element in the vertical direction; meanwhile, the contact nonlinearity between the valve elem

Volker Brendel,Stefan Kurtz,Xioakang Panytical approach, based on the Novozhilov’s nonlinear thin shell theory, is developed; the approach is suitable for treating homogeneous isotropic shells. A meshless method is considered to reduce the partial differential equations (PDEs) to a set of ordinary differential equations (ODEs): the displa

Seishi Ogawa,Yasuhito Nanya,Go Yamamotonted. Traditionally, the analysis of nonlinear systems involves studying the relation between the nonlinear frequency and the resulting vibration amplitudes. One approach is to compute the conservative (undamped-unforced) backbone curves of the system and compare them to the numerically computed for
