The smoothed frequency responses are shown to be connected with modal density, and, depending on the number of terms which are takem in the expansion, are capable of exhibiting influences of point of excitation, point of response, and participation of the various modes of vibration.

We then study the computational aspects of the frequency response gain of sampled-data systems, by comparing these three methods through a numerical example 展开 关键词: frequency response matrix algebra sampled data systems FR-operator approach bisection algorithm frequency response gain computation ...
Accurate modeling of damping in structures is of great importance for vibration response analysis and control. This paper addresses the issue of identification of damping matrix of a structure by posing it as a finite element damping matrix updating problem. Many of the current updating approaches, ...
Frequency response function is defined as the Fourier transform of the time domain response divided by the Fourier transform of the time domain input. Eqs. (4.1) and (4.2) can be written in a form of matrix: (4.15)[M000]·{z¨V¨}+[c0−Β·lLe/R]·{z˙V˙}+[KB·l/R0(R+Re...
damping, the response exactly at a natural frequency tends toward infinity. This means that it is not possible to solve an undamped frequency response problem at, or close to, a natural frequency. The numerical formulation will give a singular, or at least ill-conditioned, system matrix. ...
Fundamentally a frequency response function is a mathematical representation of the relationship between the input and the output of a system
Set the system time, input, and response data to vertical vector format. t = t'; u = u'; y = y'; Plot the system response over time for the two masses. plot3([1 2].*ones(size(t)),t,y) set(gca,Ydir="reverse") xticks([1 2]) xticklabels("Mass m_"+[1 2]) ylabel("...
