| Abstract: | The minimum curve radius is one of the main standards of high-speed railway, and it is a major influencing factor for train running. A method of calculating curve radius of high-speed railway based on the best train-line dynamic characteristics was introduced. Based on the dynamic simulation method, relational models of train-line dynamic characteristics and curve parameters were built up. By using these models, curve parameters meeting safety and riding comfort of train running were determined. By considering the best train-line dynamic characteristics and engineering technical conditions synthetically, the minimum curve radii of high-speed railway for passenger traffic were suggested. |
