Rayleigh’s quotients and eigenvalue bounds for linear dynamical systems

Autor: Rubens G. Salsa, Daniel T. Kawano, Fai Ma

Publikováno v: Archive of Applied Mechanics, vol 92, iss 3

The primary objective of this article is to demonstrate that Rayleigh’s quotient and its variants retain the usual properties of boundedness and stationarity even when the linear vibratory system is non-classically damped, extending previously acce

Parameterized Structure-Preserving Transformations of Matrix Polynomials

Autor: Daniel T. Kawano

Publikováno v: The Electronic Journal of Linear Algebra. 36:723-743

This paper examines the relationship between the companion forms of regular matrix polynomials with singular leading coefficients. When two such polynomials have the same underlying finite and infinite Jordan structures, it is shown that their compan

We consider the class of real second-order linear dynamical systems that admit real diagonal forms with the same eigenvalues and partial multiplicities. The nonzero leading coefficient is allowed to be singular, and the associated quadratic matrix po

The decoupling of defective linear dynamical systems in free motion

Publikováno v: Kawano, DT; Morzfeld, M; & Ma, F. (2011). The decoupling of defective linear dynamical systems in free motion. Journal of Sound and Vibration, 330(21), 5165-5183. doi: 10.1016/j.jsv.2011.05.013. UC Berkeley: Retrieved from: http://www.escholarship.org/uc/item/3p63p2cq
Journal of Sound and Vibration, vol 330, iss 21

It was demonstrated in two earlier papers that there exists a real, linear, time-varying transformation that decouples any non-defective linear dynamical system in free vibration in the configuration space. As an extension of this work, the present p

On modeling and simulation of tethered systems with sharp, rough contacts

Autor: Daniel T. Kawano

Publikováno v: Communications in Nonlinear Science and Numerical Simulation. 16:550-565

We extend the analysis of a reeled, tethered system in a constant gravitational field by (i) proposing a differential–algebraic representation when the tether is inextensible and (ii) examining the interaction between the tether and a sharp, fixed

It is well known that the free motion of a single-degree-of-freedom damped linear dynamical system can be characterized as overdamped, underdamped, or critically damped. Using the methodology of phase synchronization, which transforms any system of l

Righting and turning in mid-air using appendage inertia: reptile tails, analytical models and bio-inspired robots

Autor: Robert J. Full, Ardian Jusufi, Thomas Libby, Daniel T. Kawano

Publikováno v: Bioinspiration & Biomimetics. 5:045001

Unlike the falling cat, lizards can right themselves in mid-air by a swing of their large tails in one direction causing the body to rotate in the other. Here, we developed a new three-dimensional analytical model to investigate the effectiveness of
