Geometry And Static Research On The Flexible Suspension Catenary System

With the rapid growing of the global economy, and with the operation of high-speed trains in Western Europe, Japan and other countries, which carrying the speed of more than 300km/h, the high-speed railway that changes with each passing day has swept all of the world.After taking a close research, to shrink the drop is a good way to ensure the suspension catenary in the same high level. In order to accomplish this goal, this thesis use the parameter to simulation the catenary, has established the finite element model about the catenary which has the different type of hang way. To shrink the length of the drop to computations the length of the drop through repetitive process and I also make a research on the static elastic problem about the catenary base on the result of former computation. And I have extracted the static elastic nonuniformity coefficient and it's standard deviation. Base on the former computation about the FEA model can get the static characteristic about the various type of catenary. The parameter input completely in the process, and it's also a kind of new attempt in the traditional APDL process. It can make the catenary hanging to the stipulation position, and it can also make the computation more precise about the length of drop. The model is much closer to the reality,and the analysis results are more useful for reference.
