Testing the fatigue strength of a container freight wagon at MFL

The fatigue strength tests are used to check that the rail vehicle can withstand the operational loads. There are different test methods for determining the operational strength, such as static tests or impact tests. An important part of this is the pressure frame test, in which the vehicle frame is subjected to loads in an empty and loaded state. The mobile compression frame has proved particularly effective in this respect. With PJM's own development, it is possible to carry out the tests directly at the manufacturer's premises and to use the infrastructure on site or in the vicinity. This was recently the case at Maschinenfabrik Liezen, which offers a perfect infrastructure. For an Italian wagon manufacturer, fatigue tests according to EN 12663 were carried out with the mobile pressure frame.

200 km/h on the Westbahn: Vehicle tests applying a digital measuring system

The private railway WESTBahn is operating in 2-hours-cycles from Vienna via Linz to Salzburg. The fleet consists of double deck trains of the type KISS by Stadler Rail. Henceforth, parts of the fleet will be operated by DB. For the extended approval of Germany, PJM was in charge of the type tests in the field of brakes and acoustics. "The test runs were successfully performed in a very short time frame", says Martin Joch. The three main factors for this were:

  • Due to a limited timetable, the "Corona weeks" in March were ideal to perform the test runs.
  • To a great extent, the measurement chain was digitalised. The advantages of a digital measurement system are the reduced cabling efforts and a much higher interference resistance. Within a short period, our team had implemented a measuring system comprising 200 sensors.
  • The many years' experience and great committment of our measurement team.

The static tets, dynamic brake tests and tests of the wheel slide protection system were performed under varying conditions, such as differing conditions of the track and varying speed ranging from 80 to the maximum of 200 km/h.
