Simulative Study on Effects of Numerical Solution and Contact Parameters of Direct Time Integration Methods towards Stick-Slip Related Disk Brake Vibrations

Publikation: Beitrag in Buch/Bericht/KonferenzbandBeitrag in einem KonferenzbandForschungBegutachtung

Abstract

Vibrations excited by stick-slip transitions exist in numerous applications. A vehicle’s disk brake system, based on the principle of frictional dissipation, is one of them: During low speeds, so-called creep groan vibrations can occur. With increasing numbers of electrified drive trains and automated driving functions, vehicles become more and more prone for this issue of comfort and quality. Currently, no industrially applicable simulation tools are existent for the prediction of this phenomenon. Direct time integration could be one option for the future,
however, its setup of numerical solution and contact parameters was so far not treated. This work intends to answer open questions on explicit and implicit time integration of such severe discontinuity problems.
