This paper presents several new baseband methods of component mode synthesis (CMS) for non-proportionally damped systems. In contrast to most existing CMS approaches, these methods are based upon a first-order state-space formulation which engenders complex-valued modal vectors, transformation matri
For linear discrete non-classically damped systems, it is shown that truncated orthonormal and biorthonormal eigenvector matrices can be developed for the purpose of uncoupling the physical equations of motion in a truncated ordered set of normal co-ordinates. This approach avoids for large systems
An inverse non-linear force vibration problem based on the iterative regularization method, i.e., the conjugate gradient method (CGM), is used to estimate the unknown time-dependent external forces in a damped system having time-dependent system parameters by using the measured system displacement.
An empirical non-linear damping model, for use with single-degree-of-freedom clamped-clamped beam vibrations driven by band-limited white noise, is calibrated by using large amplitude experimental measurements. To verify the model, two parameter estimation methods are initially tested on simulated d
