... 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...

... signal consists of two components respectively induced by the transverse modal oscillation and the circumferential modal oscillation. Analog to the signal analysis, the flexoelectric sensitivity is also studied in two forms: a transverse sensitivity induced by the transverse modal oscillation...

...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...

... as a relative output multiplicative model perturbation. For the design of a controller for isolation of the engine vibrations from a flexible subframe, stability and performance are insignificantly affected by the model errors introduced. The special form of mixed sensitivity optimization involving three...

...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...
