1D14 Examples for European assessment of vehicle's dynamic running behaviour(Vehicles-Dynamics)

抄録

This presentation illustrates the European assessment process of dynamic running behaviour of vehicle's according to EN 14363 based on two examples from Alstom ≫ High speed tilting train ETR 610 of SBB and Trenitalia for operation in Switzerland, Italy and Germany; ≫ Three-axle shunting locomotive H3 with an axle load of 22.5t and a hydraulic radial steering system. It includes a description of the principles of the on-track test procedure with the assessment quantities and the data evaluation process. The test program of on-track tests including the instrumentation of the test vehicles is presented as well as test results related to running safety and track loading. This covers also aspects related to failure modes of the tilting system, an anti-yaw dampers or a steering system. The test results of the trainset ETR 610 achieved in an excessive test campaign in three countries showed compliance with the requirements. For the highest values of the lateral wheel force sum only a small margin remained to the Prud'homme limit as well in very small radius curves and in large curve radii. These maximum values occurred at different wheelset positions inside a vehicle. Further it was demonstrated, that running safety and track loading is not significantly affected by failures of the tilting system. The demonstration of compatibility between a tilting train and infrastructure is subject to further line homologation tests and regular inspection of each line, where these trains are operated with cant deficiencies above 150mm. The test results of the locomotive H3 showed, besides the demonstration of compliance with the requirements, that the quasi-static guiding forces remained with a good margin below the demanding limit values of 60kN in spite of the high axle load of 22.5t.
