... the ability to place a sensitive instrument near or at a point where there is little or no vibration and to keep any point along the beam stationary without using a rigid support. The assumed-modes method is used to discretize the equations of motion, which conveniently leads to the beam displacement...

... for arbitrary boundary conditions. To aid in the design process, this paper also characterizes the sensitivity of the displacement at the desired node location to parametric variations. Sensitivities are considered with respect to the base excitation frequency and the attachment mass, stiffness, and location...

... characteristics of rings. The flexoelectric modal signals and signal sensitivities of a flexoelectric layer laminated on the inner surface of the ring are studied in detail. Since the modal signal depends on ring thickness, sensor thickness and ring radius, flexoelectric signals with different design parameters...

...Marcos Satoshi Kawamoto; Rodrigo Nicoletti Embedded sensitivity analysis has proven to be a useful tool in finding optimum positions of structure reinforcements. However, it was not clear how sensitivities obtained from the embedded sensitivity method were related to the normal mode, or operational...

... is to be treated as a multi-input multioutput (MIMO) system. One of the general indices representing the stability of a MIMO system is “maximum singular value” of a sensitivity function matrix, which needs full matrix elements for calculation. On the other hand, ISO 14839-3 employs “maximum gain” of the diagonal...

... a special formulation of mixed sensitivity optimization ( 8 ). Section 2 presents the active vibration isolation application used for illustration throughout the paper. A general analysis of the impacts of structure flexibility on the open-loop transfer function is presented in Sec. 3...

...Bogdan I. Epureanu; Ali Hashmi A novel approach to determine very accurately multiple parameter variations by exploiting the geometric shape of dynamic attractors in state space is presented. The approach is based on the analysis of sensitivity vector fields. These sensitivity vector fields...

...Chulho Yang; Douglas E. Adams; Sam Ciray A novel method of experimental sensitivity analysis for nonlinear system identification of mechanical systems is examined here. It has been shown previously that embedded sensitivity functions, which are quadratic algebraic products of frequency response...
