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.

Millimetre work: measuring application for a turbine impeller

Accuracy is a prerequisite of measurement technology. Precision work is required to obtain reliable and exact measurement results. Our laboratory team is highly experienced in millimetre work. This was also the case with a measurement application for a turbine impeller. Ten strain gauge measuring channels were applied to the special aluminium-bronze surface, and calibration was also carried out in-house. Another requirement of the customer, a global supplier of electromechanical systems and services for hydropower plants, was to make the entire measuring application waterproof.

PJM's measurement know-how is not only in demand in the railway industry. Time and again, PJM also carries out measurements of stresses and loads on special machines, such as for metal shredders from UNTHA.
