About this book

The main goal of this book is to show how to modify and optimize the properties of the damping matrix in order to find the most beneficial way of adding damping to a given mechanical system. To this end, a two-degree-of-freedom model of disc brake is analyzed to gain insight into the fundamental physical behavior of damping. In addition, more realistic, high-dimensional finite element brake models are studied and optimized for stability.

Table of Contents

Frontmatter
Chapter 1. Introduction
Abstract
In mechanical engineering, self-excited vibrations are usually unwanted and sometimes dangerous.
Jan-Hendrik Wehner, Dominic Jekel, Rubens Sampaio, Peter Hagedorn
Chapter 2. Theoretical Background
Abstract
The equations of motion of a dynamical system in general are nonlinear. Since an analytic solution can only be found for some special cases, it is common practice to linearize these equations around a reference position, typically an equilibrium.
Jan-Hendrik Wehner, Dominic Jekel, Rubens Sampaio, Peter Hagedorn
Chapter 3. Optimization of a Minimal Model of Disc Brake
Abstract
In this study, the latter idea of optimizing the damping matrix is explored further.
Jan-Hendrik Wehner, Dominic Jekel, Rubens Sampaio, Peter Hagedorn
Chapter 4. Optimization of Finite Element Models of Disc Brakes
Abstract
The assumptions made to derive the equations of motion in a FE environment are similar to those of the minimal model.
Jan-Hendrik Wehner, Dominic Jekel, Rubens Sampaio, Peter Hagedorn
Chapter 5. Conclusion
Abstract
In this study, the main focus lies on the modification and optimization of the damping matrix of linearized disc brake models in order to stabilize or make more stable the equilibrium solution subject to sensible constraints and thus reduce the tendency of friction-induced squeal noise.
