In the area of dynamic strength the VÚKV a.s. testing laboratory performs buffing tests, fatigue tests, and dynamic tests of buffers.
Fatigue TestsThe tests are performed in cooperation with the Dynamic Testing Laboratory of the Škoda Výzkum (Research Company). The VÚKV a.s. provides for the technical management of the test. The tests are performed in compliance with the following documents:
Buffing Tests of Railway Vehicles and Dynamic Tests of BuffersImpact tests and dynamic buffer tests are performed in compliance with the following documents:
The purpose of the impact test is to verify dynamic strength of the vehicle structure, connection between the bogies and the vehicle frame and characteristics of the bumpers. The tests are performed in one of the following ways:
The following quantities are measured in the course of the impact tests:
Running Strength TestsThe aim of the tests is to check, at carefully selected points, that the permissible dynamic stresses are not exceeded.
Running strength tests, in order to measure the effect of dynamic loading on the structure, the bogie and other parts of vehicles, are conducted on selected tracks in compliance with the following documents:
