The Influence of the Motor Traction Vibration on Fatigue Life of the Bogie Frame of the Metro Vehicle

open access: yesShock and Vibration, 2020
During the service life of metro vehicles, the cracks frequently appear at the root of motor seats. This indicates the previous antifatigue designs are unable to cover the actual operating environment. Some individual loads, such as motor vibration, have

Evaluation methods for rail transit projects [PDF]

open access: yesTransportation Research Part A: General, 1989
The demand for rail transit funds greatly exceeds available monies. Worse, there is widespread disagreement over the wisdom of building rail systems in American cities. The Urban Mass Transportation Administration's (UMTA's) transit analysis methods have relied on cost-effectiveness measures with little attention devoted to the analysis of economic ...
