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.

Approval tests in Ireland for Geismar Italia S.p.A

Two types of track inspection vehicles will be in operation on the Irish rail network in the future. For the approval tests, the world-renowned manufacturer of track construction machines relied on PJM's expertise. The approval tests took place in Ireland - typical Irish weather included.

Dynamic tests, instrumented wheel-sets and simulation for Rhaetian Rail

Projects always take our measurement technology team to particularly beautiful places. This was also the case recently in Switzerland. The Rhaetian Railway makes railway hearts beat faster. The track is one of the most beautiful in the world, and the Bernina and Albula lines are even UNESCO World Heritage Sites. In addition to the picturesque landscape, the technical requirements are fascinating. Typical for the metre gauge track are curves up to 45 m radius and gradients up to 70 ‰. The Allegra multiple-unit train made by Stadler AG, which is used on this line in various vehicle configurations, is perfectly tailored to these high line requirements. In order to test the running characteristics of different train compositions under special operating conditions, PJM was commissioned with running tests.

The project was carried out in several parts by the experienced system specialist from Austria:

In the preliminary stage, the wheel-rail forces as well as occurring buffer forces were determined by simulations. In this way, critical conditions or constellations could be resolved computationally. Another advantage is that this keeps the metrological effort to a minimum.
Instrumented wheel sets, accelerators, transducers as well as measuring buffers were prepared in the usual way at the company's location in Graz and then installed on the test vehicle at the RhB main workshop in Landquart.
The measurement campaign was carried out on the track between Poschiavo and Alp Grüm. In real operation, the running behaviour was tested under increased operating forces. The test runs took place in November 2022. The data analysis and report were recently completed.

Mobile calibration test rig for instrumented wheelsets

Precision is the top priority in metrology, and calibration is a crucial factor. To ensure measurement reliability even for projects on site, PJM has developed a mobile calibration test stand. The advantages:

After reprofiling the measuring wheel sets, recalibration can be performed on site.
The new type of test stand enables unprecedented performance.
The test stand is easy to transport and is therefore ideally suited for worldwide use.

The mobile calibration test stand has already proven its worth during the first "field test" and was used in a project for the Rhaetian Railway. Thus we can react quickly and flexibly to customer requirements even under challenging conditions.

Static strength measurements in the factory enabled by a mobile pressure frame

The key data of Plasser & Theurer's 09-3X track tamping machine are impressive: 80 tonnes net weight, 35 m length, 8 axles, and 3-sleeper tamping units ensure powerful and efficient working. To determine the stresses and deformations of the vehicle frame, PJM carried out pressure frame tests according to EN 12663-1. The strength tests were performed at the Linz factory of the technology leader and manufacturer of track maintenance machines. This has clear advantages for the machine manufacturer: the entire on-site infrastructure is used and any adaptations to the object can be coordinated with the design engineers and immediately implemented. Using PJM’s mobile pressure frame allows the tests to be carried out directly in the factory.

Thanks to its modular design, the pressure frame is suitable for every type of vehicle. It has proven its effectiveness in static tests in numerous projects.

"Testing with the mobile pressure frame at the customer's site provides full transparency for the calculation engineers with regard to test procedure. It also greatly facilitates validating the calculation models. This approach ensures the least possible amount of time is spent in projects," explains Martin Joch, CEO of PJM. "PJM handled the measurements very efficiently and professionally. We greatly benefitted from the fact that they were carried out on our premises in Linz," confirms Andreas Pumberger, Head of Railway Testing Lab, Plasser & Theurer.
