Modeling snow accumulation in the bogie region caused by train slipstream based on sliding mesh and particle capture criteria

open access: yesAlexandria Engineering Journal
The accumulated snow swept by the high-speed train's slipstream tends to aggregate on the train's bogie, thereby posing a significant threat to operational safety. In this paper, utilizing the sliding mesh technique and a novel particle injection scheme,

Reducing the Diameter of Freight Vehicle Wheels – The Suitability of Q/D as a Control for Wheel-Rail Contact Stress [PDF]

open access: yes, 2013
High wheel-rail contact stress is related to rail damage mechanisms such as gross plastic flow. Such high contact stresses are often generated by freight vehicles which have comparatively high axleloads.

Improved method for detecting weak abrupt information based on permutation entropy

open access: yesAdvances in Mechanical Engineering, 2017
As a dynamic detecting method for abrupt information, permutation entropy could effectively reflect the subtle change in time series data, which is also simple and can be computed conveniently.

Economic Comparison of the Use of Tyres, Wheel Chains and Bogie Tracks for Timber Extraction

open access: yesCroatian Journal of Forest Engineering, 2006
Many logging operators in Finland use bogie tracks and wheel chains all the year round and under all terrain conditions. The hypothesis tested here is that bogie tracks and wheel chains increase the resistance forces, and thus fuel consumption, when ...

Shermans in Sicily: The Diary of a Young Soldier, Summer 1943 [PDF]

open access: yes, 2012
Fifty five years ago, one of the biggest news stories of the summer was the invasion of Sicily by Allied Forces. For some, the memories will never fade because they were in the front lines of the first successful Allied push into occupied Europe.

Modelling and analysis of wheel replacement and restoration [PDF]

open access: yes, 1990
"Given this system with its inherent constraints, what is the relationship between the stock of spare wheelsets on hand and the probability of not having a wheelset of the correct size on hand to effect a wheel change?
