Dynamic Component Testing

Dynamic component testing is performed at the Dynamic Test Laboratory (DTL) that forms a part of VUZ Testing Laboratory No. 1462 accredited according to ČSN EN ISO/IEC 17025. We provide services in the field of testing of rail vehicles, road vehicle parts, infrastructure and other engineering areas.

We perform tests in accordance with technical specifications, directives and standards and based on particular requirements of our customers in the field of dynamic strength and durability.

Our customers rely on the highly qualified staff of the VUZ laboratory. Our laboratory is the right choice for orders in the field of both destructive and non-destructive testing. We are ready to meet individual requirements in the field of mechanical engineering.

We offer great variability of tests thanks to the modular construction of test benches.


Brake test bench for thermomechanical wheel tests

We put emphasis on investments in new technologies, and we can therefore offer added value in the form of a unique air conditioning system, contactless measurement of wheel rim deformation, automatic real-time data collection, etc.

Draw gear and buffer gear tests

Tests of draw gears and buffer gears are performed by means of top-grade equipment. Highly efficient simultaneous testing of several components assures fast and efficient test execution.

Rail fastening tests

Modern railways place high demands on rail fastening systems. We actively follow new development trends in this area and thanks to that we are able to respond flexibly to the requirements of standards and demands of our customers.

Bearing Test Bench (BTB)

This unique device designed to test performance of axle bearings is powered by an electric motor that can simulate speeds of up to 300 km/h.

Axle and wheel test bench

This part of the DTL portfolio belongs to the traditional ones. Wheels and axles are an essential component of every type of rail and road vehicle and they are in the centre of our attention.

Non-Destructive Testing (NDT)

Determining the condition and quality of the material under test is an important task in the field of product testing and diagnostics. Our laboratory offers experience and tradition in non-destructive testing.

Seat testing

On top of comfort, the main property tested in case of seats is safety. The seat design has been moving forward continuously, and that is why we pay active attention to this area and related new knowledge.
