Rearch Of Suspended Monorail's Plane And Profile Design Parameters

With the increasing population of the city,public transport pressure is increasing,so that urban rail transit that is the most important role to relieve the public transport pressure has been a great development.Suspended monorail that is a new type of urban rail transit will be one of the important part of the urban rail transit because of its special advantage.But at present there are no examples of operation and temporary code for design.Therefore researching the plane and profile design parameters has great significance for development of suspended monorail.This article comes up with the calculation method of plane and profile design parameters and calculates the value of these parameters form the static perspective by comparing the difference and similarities between suspended monorail and traditional rail system,and referencing the calculation method of urban rail transit plane and profile design parameters.The main work is as follows:(1)The paper clears the structure of suspended monorail and running mechanism,compares the difference and similarities of technology between German and Japan,researches the structure of track beam,compares the difference and similarities between suspended monorail and traditional rail system.(2)The paper researches the main parameters of railway plane.Calculating the value of length of the straight line between two curves.According to the characteristic of this system,it's appropriate not to set up superelevation,and deriving calculational formula of minimum curve radius and calculating its value.The paper determines the linetype of transition curve,calculates the minimum curve radius when not setting up transition curve,derives the calculational formula of the length of transition curve and calculates its value in different conditions,deriving the calculational formulas of widening of distance interval between tracks and calculates the value of widening of distance interval between tracks in different conditions.(3)The paper researches the main parameters of railway profile.The paper determine the limiting condition of setting up vertical curve and calculate the its value in different conditions,derives the calculational formula of minimum length of slope segment based on different limiting conditions.The paper calculates the value of clip slope segment.
