Viscous vs. Structural Damping in Modal Analysis
It is shown that among the various damping mechanisms that are generally encountered in a mechanical structure, only the “viscous component” actually accounts for energy loss. The remaining portion of the damping force is due to non-linearities, which do not dissipate energy. Consequently, a linear model of a vibratory mechanical system involves only viscous damping, although the damping factor...
متن کاملDamage identification of structures using experimental modal analysis and continuous wavelet transform
Abstract: Modal analysis is a powerful technique for understanding the behavior and performance of structures. Modal analysis can be conducted via artificial excitation, e.g. shaker or instrument hammer excitation. Input force and output responses are measured. That is normally referred to as experimental modal analysis (EMA). EMA consists of three steps: data acquisition, system identificatio...
متن کاملMass Properties Identification of a Rigid Body Using Modal Analysis
In performing vibration analysis of the car engine on the engine support, it is necessary to know the mass properties of the engine including mass, position of the center of mass and mass inertia moments. Because the car engine has a relatively complex geometric shape and is composed of different components with different densities, determining its mass properties faces many challenges. There a...
متن کاملExperimental analysis for identification of bridges structural damage using Operational Modal Analysis based methods
Recent structural collapses of bridges and damaging occurred on deck and dampers of suspension bridges, are driving the development of monitoring techniques for the structural integrity assessment of primary lifelines. Structural Health Monitoring combines a variety of methods for observed dynamic systems response detection of different structural systems. Among others techniques, Operational M...
متن کاملDamping Estimation using Operational Modal Analysis
It has been observed that even though modal frequencies are well estimated using Operational Modal Analysis (OMA) techniques, damping estimation is not as accurate. The opinions on this aspect of OMA have been widely varying and no consensus or definite answers are available. In this paper the OMA procedure, data processing and modal parameter estimation, is studied with respect to proper dampi...
