Acceptance Tests of Railway Vehicle Ride Properties
Verification of ride properties is required by the following documents:
Tests of ride properties of railway vehicles are performed on test tracks and railway tracks in the Czech Republic and also abroad. For the purpose of the ride tests the VÚKV a.s. uses its instrumented car for the maximum speed of 200 km/hr. The tests are performed in compliance with the following documents:
The purpose of the tests is:
The testing laboratory is equipped to carry out tests according methods as follows:
Safety Against Derailment under Longitudinal Forces in S-shaped Curves
Safety against derailment in S-shaped curves is required by the following documents:
The tests are performed on a special track within the premises of the Railway Testing Track at Cerhenice in compliance with the following documents:
The purpose of the tests is to find out whether the tested vehicle is capable of safe running under the effect of push forces. The tests are performed with empty vehicles equipped with the necessary sensors and included in the test train of the prescribed composition. The train is pushed along the test rail. The required longitudinal compressive forces are acquired by braking of the front locomotives of the train. In the course of the test a set of required quantities is measured.
Body to Bogie Yaw Torque Measurement
The test is carried out through simulation on a measurement turntable in compliance with the following documents:
The purpose of the test is to measure bogie rotation torques, both with empty and loaded vehicles.
The test is performed by turning the bogie at the prescribed speed and angle with measurement of force needed for the bogie turning.
