Error Caused by Damping Formulating in Multiple Support Excitation Problems
Applied Sciences, 2020 The effect of multiple support excitation is an important issue in studying large-span structures. Researchers have shown that the damping related terms in the equation of motion can induce errors in the analysis. Wrongly modelling the damping matrix can

Research on Damping Engagement Methodology in Dynamic Analysis of Isolated Structure
Shock and Vibration, 2021 Damping has a significant influence on the calculation of structural seismic response. In this paper, we compare the commonly used viscous damping (Rayleigh damping (RD) and Caughey damping (CD)) in combination with the isolated structure test.

RHEOLOGICAL INTERPRETATION OF RAYLEIGH DAMPING [PDF]
Journal of Sound and Vibration, 1997 Damping is defined through various terms such as energy loss per cycle (for cyclic tests), logarithmic decrement (for vibration tests), complex modulus, rise-time or spectrum ratio (for wave propagation analysis), etc. For numerical modeling purposes, another type of damping is frequently used : it is called Rayleigh damping.

Model Updating for Systems with General Proportional Damping Using Complex FRFs
Shock and Vibration, 2020 In this paper, we propose a model updating method for systems with nonviscous proportional damping. In comparison to the traditional viscous damping model, the introduction of nonviscous damping will not only reduce the vibration of the system but also ...

Time-Domain Calculation Method of an Equivalent Viscous Damping Model Based on Complex Damping Model
Shanghai Jiaotong Daxue xuebao, 2021 The damping matrix of the complex damping model is easy to be constructed, which only depends on the material loss factor and the structural stiffness matrix.

Geometric integration of Hamiltonian systems perturbed by Rayleigh damping [PDF]
BIT Numerical Mathematics, 2011 Explicit and semi-explicit geometric integration schemes for dissipative perturbations of Hamiltonian systems are analyzed. The dissipation is characterized by a small parameter $ε$, and the schemes under study preserve the symplectic structure in the case $ε=0$.

A METHOD FOR DETERMINING RAYLEIGH DAMPING PARAMETERS OF COMPLEX FIELD
Civil Engineering Journal, 2019 Rayleigh damping model, which is still adopted by manygeneral finite element programs and widely used in analysis of engineering, leads to the inconformity of the calculating modal damping ratio with the actual modal ...
