Residual stress measurement in railroad car wheels
… good and bad (overheated) railroad car wheels is proposed. This criterion can replace the conventional “four inch" discoloration rule. The procedure for the new discrimination criterion is based on the fluctuations of the azimuthal residual stress in the tread of the wheel. This …

Improving the accessibility of in-stream water wheels
… around how to deploy and operate in-stream water wheels effectively. Several under-explored variables, namely the tip-speed ratio and blade depth ratio, have a significant influence on the power output of an in-stream water wheel. Adequately controlling these variables can improve the efficiency …

Thermomechanical and Vibrational Fatigue Life Assessment of Railway Wheels
Rail wheel failures can lead to derailment of trains, cost lives and billions of dollars to the railway industry. Therefore, it is important to understand the failure behavior of critical components of the train, especially the ones which are exposed to extreme weather conditions. This …

Development and Execution of a Testing Strategy for Omnidirectional Wheels
Omnidirectional wheels enable robots to achieve holonomic motion; however, this often comes at the cost of increased rolling resistance compared to traditional caster wheels. The rolling resistance in omnidirectional wheels is higher than in many other wheels due to several factors including an …

Mechanical Analyses of Multi-piece Mining Vehicle Wheels to Enhance Safety
In this research, experimental and numerical methods were used to analyse the performance of multi-piece wheel structures and two proposed innovative designs to enhance safety were validated by computer simulations. Fatality report analyses revealed that the majority (90%) of the multi-piece wheel …
