Hopf-bifurcation-curve-limited braking torque distribution for avoiding friction-induced vibrations in disc brake

Journal of Low Frequency Noise, Vibration and Active Control
Friction-induced vibrations between the brake disc and pad represent a significant source of noise and vibrations in automotive systems. To mitigate these vibrations, this study investigates the influence of brake force on friction-induced vibrations and

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Avoidance of friction induced vibrations on seals [PDF]

PAMM, 2008
AbstractIn many fields of technical and non–technical applications occur friction induced vibrations. If undesired, which applies to most of these oscillations, different methods exist for their avoidance or at least reduction. A recently investigated method, the systematic treatment of contacting surfaces by different techniques is shown in this work ...

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

Advanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Stability Analysis of a Linear Friction-Induced Vibration Model and Its Prevention Using Active Force Control

Advances in Mechanical Engineering, 2014
This paper presents friction-induced vibration (FIV) caused by combined mode-coupling and negative damping effects in a simple FIV model. In doing so, a new four-degree-of-freedom linear model which consists of a slider and a block is proposed and then ...
