Expanding headquarters: New hall for instrumented wheelsets

The instrumented wheelset expertise is made up of several elements that PJM combines with each other. PJM perfectly matches measurement technology, experience as an ISO/IEC 17025 accredited test centre, engineering expertise and 10 years of experience in the development and production of measuring wheelsets.

PJM has now also raised its infrastructure and technical equipment to a new level. The new part of the building has been equipped with a comprehensive range of equipment to ensure the highest levels of precision, stability and standard in metrological terms. In addition, the expanded infrastructure will enable even faster throughput times and project processing in future. The equipment includes, among other things

  • Mobile test rig for measuring wheelsets for all track gauges and calibration during test runs on site
  • Premises for the parallel production of 12 instrumented wheel sets
  • Indoor crane and two electric forklifts
  • ESD-protected working environment
  • Air-conditioned room (for consistently ideal conditions, for example when attaching strain gauges)
  • Dynamic test rig for end-of-line testing of instrumented wheel sets
  • Fine balancing in accordance with ISO13260 limits

The dovetailing of theory with practical testing experience is a great added value for our customers,’ says Martin Joch. He continues: ‘The instrumented wheelset infrastructure guarantees the highest measurement quality for every phase and every requirement. In combination with our specialised knowledge in engineering and our many years of experience in dynamic testing, we offer vehicle manufacturers a considerable portfolio of knowledge and services.’

This makes PJM a strong partner in the field of measuring wheelsets:

  • All processes and project steps relating to measuring wheelsets are handled by PJM in-house and from a single source
  • This also results in short throughput times
  • Calculation, design, production, calibration and balancing
  • Powerful telemetry system: Thanks to the extensive equipment, 12 measuring wheelsets can be operated simultaneously
  • PJM offers solutions for every application and every wheel geometry (not just standard solutions)

Analyst Certification of the American AAR WABL Committee for PJM strength calculations

PJM now also offers wheelset expertise for the leading rail freight country, the USA. The AAR WABL Committee (Association of American Railroads) has voted to approve PJM for performing strength calculations of wheels according to the S-660 and S-669 standards. This new area of expertise is also already in use on a project. "We are very pleased that we can now also offer our customers this consultancy service for the use of rail vehicles in North America," explains Martin Joch.

In the field of wheelsets, PJM has built up profound know-how over the years. Here, too, the link between calculation and testing plays a major role. The expertise includes calculations as well as the design of instrumented wheelsets.

A good start into a "projekt-rich" year

We have started into a project-rich year. Our laboratory team is currently working on new instrumented wheel sets. The engineering experts validate existing vehicles and optimise new vehicle designs using simulation and FE calculation. The test centre team is constantly on the road for vehicle tests. Our production team is constantly engaged in the production of our digital WaggonTracker technology. The projects of railway companies and vehicle manufacturers are carried out in Austria, Germany, the Czech Republic, Italy, Switzerland and Ireland, among others.

Optimised design for Stadler Rail AG

In the development of rail vehicles, a key factor is: as little material and weight as necessary, but as much load-bearing capacity as possible. Topology optimisation has been part of our everyday engineering work for years. Among others, Stadler Rail AG relies on our calculation know-how. In a current project, our engineering team is dealing with structural optimisation and strength verification of the wagon bodies of a local transport vehicle.

We think out of the box

We have a particularly effective and efficient engineering team, as experienced experts in design, calculation, simulation and certification work very closely together. Expanded by measurement technology specialists, we offer unique know-how in the product development of structural railway components. Our innovative strength is further enhanced by our distinctive out-of-the-box thinking: All engineering staff have many years of experience in the automotive and mechanical engineering sectors in addition to their railway activities. Therefore, we are not only engineering experts in rail transport, but also in projects in other sectors, such as the optimization of waste treatment plants or other mechanical engineering projects.

Best calculations for the future

With our concentrated knowledge in calculation, simulation and measurement, as an accredited testing laboratory we are well prepared when calculations and simulations are increasingly used for the approval of railway vehicles in the future. For all this, FprCEN/TS 17833:2022 comes into play, the "Guideline for the use of simulations to demonstrate compliance with technical and regulatory requirements".

We seamlessly dovetail our profound experience from worldwide test drives and approval trials with our engineering know-how. We link our empirical values from track tests with our design knowledge and thus create great added value for our customers.

Engineering expertise for developing new rail freight wagons

 
Developing new types of rail freight wagons requires a high level of engineering know-how. The basic concept of a rail freight wagon is maximum load capacity as well as a low tare weight with a maximumg safety level. Exactly these requirements are in the focus in developing a new 60ft rail freight car ordered by innofreight, the Austrian specialist for innovative systems of rail freight transport. Due to our highly experienced engineering team, PJM was the first choice: Our profound metrological know-how ensured a perfect link-up to the ral product during the whole delelopment process.
