Integrating Dynamics and Wear Modelling to Predict Railway Wheel Profile Evolution [PDF]

, 2003
The aim of the work described was to predict wheel profile evolution by integrating multi-body dynamics simulations of a wheelset with a wear model. The wear modelling approach is based on a wear index commonly used in rail wear predictions.

Influence of Chronotype on Cycling Performance in Simulated 20‐km Time Trials—A Pilot Study

Journal of Sleep Research, EarlyView.
Evening‐type athletes show improved cycling performance later in the day, whilst morning types peak earlier. These differences appear linked to variations in mental readiness and sleepiness, highlighting the importance of considering chronotype in performance planning.

Study on control schemes of flexible steering system of a multi-axle all-wheel-steering robot

Advances in Mechanical Engineering, 2016
It is well known that a multi-axle wheeled robot possesses larger load capability and also higher drive performance. However, its steering flexibility is degraded due to the large number of wheels.
