英文摘要：

Combined with the feature of high-speed railway location design,a bidirectional traction calculation element model based on the force analysis of high-speed train was established according to the most quickly traction strategy as well as satisfying conditions of speed restriction and operation restriction.The paper was proposed to realize the automatical and continual traction calculation for new high-speed railway following the ideas of continuous calculation of each element.The 3D simulation platform for the high-speed railway was built up with the combination of traction calculation and technologies of constructing the large-scale railway 3D scene.Besides,the way to calculate the roam path on the basis of the results of location design and traction calculation was given so as to realize the effect of roaming in the driver’s point of view in the 3D scene.The rationality and practicability of the method was verified by taking the traction calculation and establishment of the 3D simulation platform of train traction running in Chengdu-Pujiang High-speed Railway as an example
