This paper introduces a solution for the large-span continuous railway beam,which crosses roads by the common non-tension-resist and basin-shaped rubber support,and the beam is used in the second phase of the straddle type monorail project in Chongqing City.

This paper cites of straddled-type monorail vehicle as anekample,through using collision safety design conception,frontal crash of straddled-type monorail vehicle body has been simulated and analyzed,and safety performance and anti-collision performance have been verified.

The main features, technical parameters, structure and development of the straddle type single-rail bogies are described in fairly specific detail.

In respect to the interaction between pantographs and catenaries of the straddle-type monorail system of Chongqing urban rail transit Line 2,there occurred the uneven wear of collector slide.

Research purposes: In order to inspect the actual dynamic responses of Chongqing straddle-type monorail transportation system,dynamic loading tests were carrid out.

Present situation of current-carrying system,which is used in contact system of Jiao-Xin line for straddle-type monorail transportation in Chongqing,is introduced in this paper.

In order to discuss the dynamic responses of a straddle-type monorail transportation system,a dynamic model for a monorail vehicle with 15 DOFs(degrees of freedom) was established by employing the linear tire model.
