Friction Induced, Self Excited Vibration of a Pantograph Catenary System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A dynamic model of a pantographcatenary system is established. In the model, motion of the pantograph is coupled with that of the catenary by friction. Stability of the pantographcatenary system is studied using the finite ...
Squeal Noise of Friction Material With Groove Textured Surface: An Experimental and Numerical Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, an experimental and numerical study is performed to understand squeal generation and suppression of a padondisk friction system. Several friction material specimens having various orientation degrees of grooves ...
