Urban Rail Vehicles, The Automatic Door System,

Aims at the automatic sliding plug door system for urban transit vehicle, this thesis, with its achievements listed below, makes a quite deep research into the theory and technologyinvolved with the localization of the subject door system.1.SOLUTIONS to each component of automatic sliding plug door system for urban transit vehicle including operator, door leaf and control system come up in accordance with the technical specification of door system, and subsequently the R&D and design of automatic sliding plug door system has been finished.2.A PIONEER DESIGN - Mechanical locking device free of power supply characterized by unidirectional and self-locking function is adopted for the first time based on deep research as well as considerable trial on the locking device of existing door system.3.FEA ANALYSIS is used for the theoretical calculation of the rigidity of door leaf so that the safety, reliability and availability of sliding plug door system are ensured.4.HIGH-PERFORMANCE AND COMPLETELY DIGITAL CONTRL SYSTEM in closed loop is established on the basis of digital signal processor (DSP) and a control strategy with the application of brushless DC motor is put forward.5.TEST AND INSPECTION PROCEDURES are drawn up in reference to international, domestic and industrial standards and test methods, which all contribute to the final establishment of a complete set of test and inspection system for automatic sliding plug door system,...
