FutureConvent: Measurement technology for young enthusiasts

What is the FutureConvent about? Companies show young people attending a technical college what sustainable topics they are working on. Higher technical colleges combine specialised technical training with a school-leaving certificate. The conference programme was rounded off with lectures and workshops. The young people were given an insight into the technologies of today and the future.

PJM was at the FutureConvent for the first time and presented smart rail monitoring using laser technology. The students were also able to flex their muscles: The force transducer was used to measure arm strength.

New test area: PJM accredited for pantograph

PJM has expanded its scope as an accredited test center in accordance with ISO/IEC 17025 and now also tests the dynamic interaction between pantograph and overhead contact line. In addition to measurements in accordance with EN 50317, the accreditation also includes simulations in accordance with EN 50318, making PJM the only company in Austria with accreditation for the specialist area of pantographs.

Over the past two years, the Austrian system specialist has invested in the infrastructure of the new department. The pantograph test rig for calibrating the measuring system - as well as the technical equipment for other areas - has been set up at the company's site in Graz. Extensive tests in the wind tunnel have proven that the measuring system is non-reactive. With the existing measuring equipment, tests can be carried out with up to two measuring pantographs, which means that multiple-unit operations can also be realised. The requirements for the interaction between pantographs and the overhead contact line system of the new service jet for ÖBB had been tested in summer (as announced in the media release: https://pjm.co.at/wp-content/uploads/2024/06/PI-PJM-Servicejet-6-2024-DE-Web2.pdf). In the coming weeks, the measurement technology team will be testing another rail vehicle in single and multiple-unit operations.

‘Due to decarbonisation, the focus will be on electric rail vehicles in the future. With its corresponding expertise and infrastructure, PJM is ideally positioned for the new specialist area,’ says Martin Joch, CEO of PJ Messtechnik GmbH. With the new specialist area, PJM offers several advantages for clients, such as the efficient sequence of the various tests for rail vehicles. The expertise in the area of simulations offers particular added value: ‘Simulations significantly minimise the testing effort for multiple tractions. Theoretical calculations allow the large number of variants to be reduced to relevant train combinations, which are then tested in dynamic track tests. This saves valuable time and reduces costs,’ says Martin Joch.

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.

New 80ft InnoWaggon Sggns: PJM carried out overall accreditation tests

When it comes to further development or new concepts, rail logistics specialist Innofreight is an important address. Recently, the wagon fleet was expanded by a one-piece 80ft InnoWaggon Sggn. Less wagon weight but more train load were the requirements to make rail transport even more economical and efficient for Innofreight customers. For the overall approval, the company relied on PJM expertise. The various tests were evaluated in several stages:

Fatigue strength: The strength tests were carried out by the PJM engineering experts according to EN 12663. Another task of the engineering team was to optimize the strength. The static tests were carried out by means of a mobile pressure frame at the site of MFL Liezen. The buffing impact tests took place mainly in St. Michael, not far from Innofreight's headquarters.
Brakes: The static and dynamic tests according to TSI WAG:2020 were also carried out in the St. Michael area. The uncoupling tests were carried out with various loading conditions.
Acoustics: The acoustic measurements according to TSI NOI 2014/1204/EU were used to determine pass-by noise, rail roughness and track decay rate.

This project included two novelties:

Uncoupling device: For the first time, a new device developed by PJM was used for the suspension tests. The new component has proven itself very well since it is lighter, smaller and easier to operate.
Solar energy: The measuring instruments were supplied with energy by means of a solar panel. The panel can be set up in just a few steps and provides sufficient power for the measurement tests in good weather.

Lecture at International Railway Vehicle Conference in Dresden

A fixture among railway experts is the 1.5-yearly International Rail Vehicle Conference in Dresden (Internationale Schienenfahrzeug-Tagung). This year, PJM and voestalpine Track Solutions Germany GmbH also provided first-hand know-how. In the conference section wheel / rail, an insight into "rail maintenance based on smart measurements" was presented. The innovative approach of using mobile measuring technology to measure the rails and tracks of entire trams and underground trains in a short time was awarded the state prize.

The Rail Vehicle Conference was organised by the Faculty of Mechanical Engineering at the Dresden University of Applied Sciences, the Faculty of Transport Sciences "Friedrich List" at the Dresden University of Technology and DVV Media Group GmbH | Eurailpress Hamburg. Around 500 participants discussed innovations in the railway industry in a beautiful setting on the Elbe.
