Title: A method for measuring the system damping
Inventor: LI WEN-LUNG
Filed: 2003-01-27
Abstract: In general, there are three parameters for a structural dynamic system. They are mass, damping and stiffness parameters, which characterize the system. Among them, the mass and stiffness may be computed from a numerical simulation software package like a 3D finite element method. However, the system damping can be obtained only from direct measurement. As the consequence, a correct method to measure the system damping is essential and necessary. The present method provides a way to measure it from an experiment of exciting the system by an externally harmonic excitation. The next step is to modulate the steady-state responses of the system by the harmonic excitation. Once the measurement is complete, one is able to get the direct current (dc) of the modulated responses. That is, (1) by using a low-pass-filter to filter out those of time-variant part, or (2) by using the complete cycle integration for the modulated responses, the dc part can be obtained. In fact, that dc part is related to the cosine value of the system damping. The present patent also provides a formula to derive the true system damping the dc signal. Unlike most commonly used methods, the present patent does not require the system damping to be small. Therefore, the new method can be applied to critical- and over-damped systems. In case the present method is applied to measurement for each sampling step and directly shows the result to the window, it is possible to monitor the system damping. In addition, the instrument may have one more useful function.
