Application of a Frequency Converter in Electric Automatic Control of Central Heating by Jingwen Yin, Guifeng Zhang

“…The experimental results show that the temperature control strategy using a frequency converter automatic compensation method reduces the energy waste caused by manual regulation to a certain extent. When the speed of a water pump motor decreases to 4/5 of the original, the power consumption will decrease to about 52% of the original and save about 48% of the power; When the speed drops by 3/5, the power consumption is about 22% of the original, saving about 78% of the power. …”

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. …”
