Abstract
The vehicle unit basic resistance model is established together with its mathematic expression on the basis of basic resistance, curve resistance, ramp resistance, wind resistance and switch resistance undertaken by vehicles. Vehicle parameters and wind resistance parameters are used to analyze and calculate vehicle-related conditions. Research results show that all longitudinal grades even a flat one may give rise to potential slipping and measures must be taken to ensure safety. This paper evaluates the standard of station line longitudinal grade stipulated in Yard Specification, puts forward measures and calculation method to improve vehicle parking by means of stop retarders. Retarders can be used to increase longitudinal grade of the loading line to meet the requirement for quantitative and fast loading or that for rail weighbridge measurement system, which makes contribution to provide the basis for line longitudinal slope design, extend the application of station speed regulating device and innovate the engineering design method, and to serve as a theoretical basis for the engineering comprehensive optimization design and as reference for design and calculation.关键词
