Nonlinear active vibration damping
IEEE Transactions on Automatic Control, 1994Summary: A multivariable nonlinear controller is investigated for vibration suppression of flexible structures. The closed-loop gain matrix consists of a varying term added to a constant term. The varying term is proportional to the measured signal, providing rapid cancellation of large deflections and maintaining low noise sensitivity.

This chapter presents analytical successive approximations algorithms for different oscillators with strongly nonlinear characteristics. In general terms, such algorithms approximate temporal mode shapes of vibrations by polynomials and other simple functions of the triangular sine wave.

Nonlinear Vibrational Spectroscopy
2013Second order nonlinear spectroscopies such as sum frequency generation (SFG) are intrinsically interface sensitive and enable sub-monolayer sensitivity to be achieved at buried, optically accessible interfaces. Vibrationally-resonant SFG allows bond (functional group) selective in-situ spectroscopy of interfaces as diverse as solid-solid, liquid-liquid

Accurate Approximations for Nonlinear Vibrations
2019As global issues such as climate change and overpopulation continue to grow, the role of the engineer is forced to adapt. The general population now places an emphasis not only on the performance of a mechanical system, but also the efficiency with which this can be achieved.

Nonlinear Antiresonance Vibrating Screen
2012A mathematical model of two masses vibrating screen with nonlinear elastic and dissipative ties working under ideal harmonic excitation is considered. The focus of the article is the study of the stationary movements in the “antiresonance” zone between the two natural frequencies.

Control of Nonlinear Vibrations
2014In this chapter, methods which can be used to control nonlinear structural vibrations are discussed. Introductory examples showing the control of linear and nonlinear single-degree-of-freedom oscillators have already been discussed in Sect. 1.4 of Chap. 1. This chapter extends the ideas presented in these introductory examples to a range of controllers,
