Abstract
Due to the complicated route condition, rapid vehicle speed variation, and diversified operation modes, elevation design of rail curve is faced with complicated working situations. Based on the design principles for super elevation calculation and superelevation factor limits, this paper focuses on superelevation calculation methods and program realization under such working conditions as single-speed mode, multi-speed mode, and easement curve entering platform. The results show that superelevation factor limits are selected according to different working conditions. Average speed method should be adopted for single speed mode. For multi-speed mode, optimized approaching high speed method should be adopted. In order to ease the curve entering effective platform, 15 mm should be taken as the restriction for the end platform superelevation. Using computer programming may effectively improve the design efficiency.关键词
