A Rattle Signal Denoising and Enhancing Method Based on Wavelet Packet Decomposition and Mathematical Morphology Filter for Vehicle

Buzz, squeak and rattle (BSR) noise has become apparent in vehicles due to the significant reductions in engine noise and road noise.The BSR often occurs in Cream driving condition with many interference signals.Thus, the automatic BSR detection remains a challenge for vehicle engineers.In this paper, a rattle signal denoising and enhancing method

How tribology has been helping us to advance and to survive

Abstract Movement between contacting surfaces ranges from macro to micro scales, from the movement of continental plates and glaciers to the locomotion of animals and insects.Surface topographies, lubricant layers, contaminants, operating conditions, and others control it, i.e., this movement depends on the tribological characteristics of a system.
