Noise distribution law of air-conditioning ducts for metro vehicles
Noise Control Engineering Journal, 2022The passenger comforts are directly affected by the air supply uniformity and noise of air-conditioning duct inside the metro vehicle. In order to solve the integrated design problem of air supply uniformity and noise control of air-conditioning ducts, a theoretical model is established to analyze the air supply uniformity, noise attenuation, and ...

Reliability Analysis and Prediction of Metro Vehicles’ Bogie Frame
Applied Mechanics and Materials, 2014Frame is the main bearing component of bogie and the reliability of which directly affects the performance and safety of the locomotive. Survival analysis is used for reliability analysis of bogie frame to solve uncertain life time problem. It turns out that the best life distribution model is three-parameter Weibull distribution. A prediction model of

Research on wheel wear evolution of inside axlebox metro vehicles
Industrial Lubrication and TribologyPurpose Axleboxes are an important structure that connects the wheelset with the bogie frame. Inside axlebox bogies have lower wheelset yaw angle stiffness and better curve-passing performance. The purpose of this paper to study the differences in the wear evolution law and the influencing factors of the two types ...
