Independently Rotating Wheels with Induction Motors for High-Speed Trains [PDF]

, 2011
Railway vehicles with conventional wheelsets often experience problems of lateral instabilities or severe wear when running at high speed. The use of an independently rotating wheelset (IRW) can potentially eliminate the cause of wheelset hunting and ...

Optimising low acoustic impedance back-fill material wave barrier dimensions to shield structures from ground borne high speed rail vibrations [PDF]

, 2013
Ground borne vibrations generated due to high speed train passage can cause undesirable effects on the nearby environment. One approach to mitigate vibration levels is to use "wave barriers", however their installation cost may be very high.

A new device for stress monitoring in continuously welded rails using bi-directional strain method

Journal of Modern Transportation, 2018
The technology of continuously welded rails (CWRs) is important in modern railway track structures. To measure rail stress, resistance strain gauges are preferred due to their good stability, sensitivity, and resistance to external interference. Based on

A New Mechanism of Canopy Effect in Unsaturated Freezing Soils

E3S Web of Conferences, 2016
Canopy effect refers to the phenomenon where moisture accumulates underneath an impervious cover. Field observation reveals that canopy effect can take place in relatively dry soils where the groundwater table is deep and can lead to full saturation of ...

A mathematical model of tortuosity in soil considering particle arrangement

Vadose Zone Journal, 2020
Tortuosity is an important parameter for studying the permeability of soil. Existing studies of soil tortuosity are usually of empirical nature and attempt to relate tortuosity to soil porosity alone.
