New Insights into Railway Vehicle Dynamics

Dear Colleagues,

It is widely acknowledged that developing higher-speed rail transit is important. However, higher-speed, lighter-weight, and lower-axle-load designs will lead to a sharp increase in the aerodynamic loads of the train and the sensitivity of the vehicle system to external disturbances, which will weaken the train's toughness against external disturbances and further increase the risk of operational instability. This adds new challenges to the contradictory regulation between weight reduction–speed increase, energy saving–consumption reduction, and safety–stability operation performance of higher-speed trains, which has become a restriction on the safe, efficient, and green development of higher-speed rail transit. Hence, it is urgent to research new technologies that are suitable for higher-speed trains such as aerodynamics, vehicle dynamics, and safety operation in special weather environments such as strong winds from new perspectives.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
