Influence of Polygon Wheel on Dynamic Performance of Meter-gauge Locomotive by Jingtao HU, Jiuhe YANG, Junjun DING, Zhaoxi LI, Fu LI

“…At last, the change trend of wheel-rail vertical forces was studied under the joint action of polygon wheel and track excitation. The results showed that due to the low running speed of the meter-gauge locomotive, the polygon wheel will form low frequency vibration which will increase the vibration response of the car body; the polygon wheel will greatly increase the wheel-rail vertical forces, but it has little effect on the derailment coefficient; the wave depth limit is inversely proportional to the running speed of the locomotive and the harmonic order; the track excitation will not cover the trend caused by polygon wheel, but it will greatly increase the wheel-rail vertical forces. …”

The response characteristics and stability evaluation of vegetated slope under strong wind by Yanlin Liu, Fei Wang, Feng Ji, Lianhua Zhang, Jianjun Zhao, Chen Zheng, Jibin Chen

“…At wind forces ≥ 13 (typhoon: 37.0–41.4 m/s), vegetation exerts a negative influence under the combined action of strong wind loads. (2) Based on the experimentally determined evolution of soil strength parameters, a formula c (v, w) was fitted to express the variation of cohesion with wind speed (v) and moisture content (w). (3) The optimized evaluation model demonstrates increased sensitivity compared to the traditional model, resulting in a 17.88% increase in sliding force and a 10.62–11.64% increase in anti-sliding force. …”
