Analyzed on dynamical derailment process of high speed vehicle by DDSCRH, the critical position on chmb wheel and influence factors on lateral force for derailment are obtained. Finally, high-speed vehicle dynamical simulation is verified on DDSCRH by comparing with the existing results of the line test.展开更多

This paper focuses on the industrial organization of China＇s high-speed railway industry and the applicability of the Anti-Monopoly Law. We intend to answer the following questions： （l） Why is the high-speed railway industry not an industry of natural monopoly？ Which segments of the industry have elements of natural monopoly？ （2） At the level of corporate organization, what is the legal and economic rationale behind the patterns of China＇s high-speed railway undertakings evolving from government-affiliated enterprises to special legal person enterprises and then shareholding companies？ （3） The applicability of the Anti-Monopoly Law to the high-speed railway industry. Our conclusions from the perspective of competition policy are worth referencing for similar industries such as electric power, telecommunications, and water and gas supply.展开更多
