Dynamic Responses of Different Types of Guideway Structures on Shanghai Low-speed Maglev Test Line

The National Maglev Technology R&D Center (NMTC) has been doing research on low-speed maglev technologies since 2005. The Shanghai low-speed maglev test line was built in July 2006 with a total length of 2.0 kilometers. During the layout of the test line, situations that may arise in engineering practice were taken into account. For the guideway system, different types of structures for the main line and the vehicle maintenance line, of different spans, were produced and erected. From 2006 to 2010, numerous tests have been systematically conducted on the line, covering all sub-systems. According to experiences from the Shanghai high-speed maglev line, dynamic response of the guideway structure may have a great influence on the stable running of a maglev vehicle. During these tests, dynamic responses of different types of girders and track skeletons were recorded and analyzed, including accelerations, displacements and stresses. The responses of different parts of the guideway switch were also taken in order to make evaluations and find its weakness to guide further optimization. Through these analyses, some instructive suggestions for the design of guideway structures were acquired.
