The subject of this work is the experimental investigation and the mathematical modeling of the impact force behavior in a vibro-impact system, where a hammer is mounted on a cart that imposes a prescribed displacement. By changing the hammer stiffne

Background Skin expansion is a physiological process that is defined as the ability of the human skin to increase its superficial area in response to stress or to a given deformation. Skin expanders are silicon bags that are implanted underneath the

In the present work we describe an original image measurement method for quantifying facial changes due to aging. The first challenge was to define adequate aging parameters and how they could be measured. The analysis of these data is not trivial, s

The Magnus demonstration gyroscope is an instrument that allows a series of amazing experiences when the rotor loses its axial symmetry. It consists of a rotor on two gimbals whose inertia and energy loss will be considered in the modeling. A normali

Understanding vibro-impact systems is basic for impact dynamics used in resonance drilling. In order to model a vibro-impact system, a contact model must be chosen. The choice of the best contact model for a certain application is not an easy task. T

The study of impact systems is gaining increased interest due to many practical situations where impact affects the overall dynamics. However, there are few results in the literature leading to a clear understanding about how the dynamics of MDOF sys

Based on experimental data, this paper shows that the mathematical models of large hydrogenerators, used to preview the dynamic behavior at the design phase or as a predictive maintenance tool at the operation phase, must include the effects of the s

Volume 3B: 15th Biennial Conference on Mechanical Vibration and Noise — Acoustics, Vibrations, and Rotating Machines.
One of the main reasons for the acoustical noise and vibrations in electrical machines is the excitation of the stator due to the presence of magnetic harmonics in motors and generators. During the design of these machines one must care that the freq

This paper presents, at first, the equations of eigenvalue problems concerning non self-adjoint systems, having real matrices, for the case of rotating machines. Fixed frame approach is used, in which the bearing element matrices are not necessarily
