摘要：
Track alignment has great influence on ride comfort of high speed railway. The suitable design of route plan curve and vertical profile is crucial to the improvement of ride comfort for high-speed trains. This paper presents a ride comfort evaluation method for the assessment and optimization of track alignment from a dynamic viewpoint. In order to evaluate the vibration of trains caused by track geometrical conditions, a dynamic model is developed, which can take account of the varying of running speed. Then a case study is carried out to illustrate the evaluation method, in which the running speed curve is introduced, and the ride comfort evaluation method suitable for evaluating track alignment is analyzed.
