RISExperimental Investigation of the Time Delay Between a Varying Applied Normal Force and the Resulting Friction Force
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently, one of the present authors proposed a new model to explain the generation mechanism of brake squeal based on the time delay between a varying applied normal force and the resulting friction force. The present ...
Transient Dynamics Research on the Force-Measurement System for Hypersonic Impulse Combustion Wind Tunnel Based on Inertia Compensation
Publisher: American Society of Civil Engineers
Abstract: The signal detected by a force-measurement system (FMS) is transient in an impulse combustion wind tunnel, and the transient property of the FMS will affect the measurement result significantly. This study presents a method ...
A Root Cause of Curve Squeal: Self-Excited Frictional Vibration of a Wheelset–Track System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When a metro vehicle navigates a tight curve, it invariably causes a squealing noise. Most researchers proposed the negative friction–velocity slope as the generation mechanism for curve squeal. However, some phenomena of ...
