Embodiment Construction

[0045] In the method 100 at figure 1 In the embodiment shown in , a derailment test 101 is carried out to test the travel 102 of the vehicle on the other track, here, for example, on a concrete roadway. Measurement data 104 are acquired during drive 102 . During the travel 102 of the test vehicle on the concrete roadway, the test vehicle is dragged along the test travel section here, including masses, springs, dampers and wheels to which the wheels are connected via springs and dampers. However, the tests can also be carried out on other roadway configurations, for example on asphalt roadways, on roadways with different sleeper heights and sleeper configurations, etc.

[0046]The test track is formed by way of example from a concrete roadway, as is present in certain embodiments of the slab track. The wheels of the test carrier roll between the rails in gaps which are filled with concrete in the slab rails used here. Different types of roadways, for example concrete, can be...

Abstract

The invention relates to a simulation model (112) for simulating the movement of the rail vehicle on the travel route, wherein a part model (116) for the contact between wheel and travel route is substituted by a wheel-surface contact model (110) for another travel route, wherein the wheel-surface contact model (110) for the other travel route is parameterised (111) on the basis of tests (101) with a test vehicle, which forms a simplified model of the vehicle, such that, with the simulation model (112) in which the wheel-surface contact model (110) is used for the other travel route, data (118) can be generated for the validation (124) of derailment detection systems (122) by carrying out simulations with the simulation model (112) for the other travel route.

Description

technical field [0001] The invention relates to a method for generating data for validating a derailment detection system of a rail vehicle, wherein a simulation model is adapted with the aid of measurement data generated during tests with a test carrier and subsequently carried out by means of the simulation model Simulations were performed to generate data for validating the derailment detection system. Background technique [0002] A device and a method for detecting a derailment of a rail vehicle are used in a rail vehicle. [0003] A method and a device for detecting a derailment of a rail vehicle are known from DE 199 53 677 C1. The vertical and / or lateral accelerations of structural elements of the rail vehicle that are in direct or indirect contact with the rail relative to the direction of travel are determined by means of acceleration sensors, and the signals of the acceleration sensors are quadratically integrated over time. If the twice-integrated acceleration ...
