wheel track vehicle
解釋
輪軌車輛-
With the speed up of railway transportation, the lightening design of vehicle seems to be more and more important. reducing the weight of vehicle can not only reduce the consumption of the raw materials and the power of traction, and increase the operation speed and improve the starting and braking performance of trains, but also has the advantageous to reduce the wheel / rail interaction forces, vibration and noise, increase the service life of the vehicle and the track, and economize the cost of transportation
隨著鐵路運輸速度的提高，車輛的輕量化顯得越來越重要，減輕車輛自重，不僅可以減少原材料的消耗，有利於降低牽引功率，提高列車的運行速度，改善列車的啟動和制動性能，而且可以有效的減少輪軌間的動力作用，減少振動和噪音，增加車輛和線路的使用壽命，節約運輸成本。 -
