A Novel Framework for Modeling Reconfigurable Dynamic Systems
… system response by analyzing the combined receptance matrix or FRFs of an assembly. This is achieved through a generalized mathematical algorithm that combines the subsystem components' Frequency Response Functions (FRFs). The approach systematically employs a reduced-order model by …

Study of Active Vibration Control using the Method of Receptances
Using the Method of Receptance, it is possible in general to assign 2_x0002_ poles (i.e. n conjugate pairs) of an axially vibrating rod of variable cross section by sensing the state at _x0002_ points along the rod. Using the sensor data, closed loop feedback control gains can be calculated by …

The development of rail-head acoustic roughness
… and smooth the peaks and troughs in the track receptance. Rail dampers also reduce the dynamic wheel-rail interaction forces, especially around the pinned-pinned resonance, and shift the force spectrum to lower frequencies or longer wavelengths. However, rail dampers are not predicted to affect …

The response of box-type structures to vibration.
… were also developed to calculate the structural receptance from the natural frequencies and mode shapes calculated using the finite element technique and damping factors obtained experimentally. From this, the response spectral density of the structure to a known excitation spectrum was obtained. …

State feedback control with time delay
… of pole assignment using data from measured receptances. This approach is extended for pole assignment for a linear vibrating system by using state feedback control delayed in time. This approach is significantly advantageous over various conventional state-space approaches which need to use …
