Changes occurring in a machine's component under continuous cyclic loads are the focus of our interest. The basic measure of such changes can be the energy loss. In order to estimate it correctly, a precise model of the vibration damping, taking into account not only the viscous friction but also the resistance to motion associated with dry friction, must be introduced. Therefore a nonlinear type model, which would describe much more accurately the dynamic properties of the tasted element of a machine then the commonly used linear model, is adopted.
The present work provides a corpus of numerous solution in this domain, worked out mainly by the autor and his team.
This book is addressed toengineering offices and groups that need people with knowledge of the testing of machanical systems under complex dynamical loads. The methods presented can also be used in material labolatory testing specialized particulary in an evaluation of dynamical properties of modern materials.
