Theme Articles on Mechanics of High Speed Rail-

Abstract: In the preceding theme issue on “Current research progress on mechanics of high speed rails” (Acta Mechanica Sinica, 30: 846–909 (2014)), we invited several authors in the field to present their research on high speed rails (HSR).In order to develop a comprehensive understanding about the dynamics and long-term durability of HSR systems, there is a prevailing need for new research from multidisciplinary groups. The theme articles published in this issue are the result of our continual endeavors to introduce cutting-edge research on the mechanics of HSR, from researchers of different backgrounds and working on different aspects of the system. One focus of the theme articles is on the aerodynamic design of high speed trains. The second focus of the theme articles is on the dynamics of train–wheel–track interaction. As discussed before, there is tremendous progress in the research of HSR systems within the past decade, boosted by the huge marketing growth in China and worldwide. With increasing population to use HSTs for long-distance travelling, we expect there could be growing research opportunities on the safety, durability, energy efficiency, and environmental friendliness for HSRs, and we look forward to seeing continual research progress on such directions.
