The other is developed to solve for frequencies of the minimum response points corresponding to a zero slope in the frequency response function curve by using the dichotomy method. In addition...

... is then found using Hamilton’s principle. Experimental modal testing is performed for the purpose of validations of the frequency response functions (FRFs) obtained from the model for the cable-harnessed plates under clamped-free-free-free boundary conditions. The results clearly show the dynamic effects...

Different from previous statistical metamodels that are built for individual...

...J. M. Liu; W. D. Zhu; Q. H. Lu; G. X. Ren Impulse response functions (IRFs) and frequency response functions (FRFs) are bases for modal parameter identification of single-input, single-output (SISO) and multiple-input, multiple-out (MIMO) systems, and the two functions can be transformed from each...

... vibration isolation feedback control transfer function coupling effects stability frequency response function In precision engineering environments, vibration isolation has become standard practice. A vibration isolator is essentially a low-pass mechanical filter. The most commonly applied...

... of truss or frame structures. In this study, the MRRM is employed to obtain the frequency response function (FRF) of displacement of a frame under the action of a unit impulse load. The natural frequencies of the frame are determined from the FRF, since the curve of FRF has peak when a resonant frequency...

The steady-state response and the stability of the solutions for various parameters are studied numerically, using the frequency response function method. The numerical results show that the system behavior includes multiple solutions...
