Technical parameters
The test bench is inteded for testing of air springs of rail vehicles. It consists of a main frame, tested air spring and weight representing 1/4 of vehicle carbody mass (max. 20 t). The air spring is excitated by a hydraulic cylinder; parameters of excitation: max. 30 Hz, amplitude max. 20 mm. Total dimensions of the test bench: 5 x 2.5 x 6.5 m. The results of the tests will be used for development of new rail vehicles.
Economical parameters
Savings of costs 2,000,000,- CZK / year (reduction of test runs with real vehicles).
