TESTING SERVICES & EQUIPMENT
Safety through knowledge and experience
When used in rail transport, air spring systems have to withstand the heaviest of loads, says Andreas Haß of ContiTech AG.
D
rawing on expert knowledge gathered in 50 years of experience, ContiTech Railway
Engineering delivers a standard of quality that guarantees safety and long service life in the tough world of routine rail operations.
A globally unique independent test laboratory and a far-reaching range of services increase both its credibility and the benefits it can offer customers.
Whether used in high-speed trains, subway
systems or freight trains, ContiTech air springs in OEM quality are up to the challenges posed by bogie technology in modern rail vehicles.
However, imitation products are now flooding the spare parts market in ever-greater numbers. These cheap air spring knock-offs from other manufacturers may look very much like the original parts. However, due to inadequate testing and processing, these products harbour high safety risks and can result in costly damage.
A whole series of research and test measures guarantee the OEM quality of ContiTech products.
In addition to computer-aided engineering, the finite elements method and multi-body simulations, these also include service life forecasting and multi-axial test rigs. In January 2012, ContiTech Railway Engineering opened the world’s
sole laboratory specialising in testing air spring systems for rail vehicles.
It has now been certified a further time. Twelve testing procedures that are important for the rail industry have been accredited in accordance with DIN EN ISO / IEC 17025.
Just as safety plays a major role in ContiTech products, so, too, does the matter of service. This covers global availability of products, a tight dealer and service network, and customer- specific solutions.
ContiTech also sets the benchmark in the field of pantographs, where long-lasting ContiTech air actuators are used in transmitting power from a permanently installed overhead line to rail vehicles, thereby ensuring uniform contact pressure both in variable weather conditions and at high speeds.

Handy solutions for vehicle assembly
Iain Caville, managing director of Measurement Solutions, says the traditional methods employed in vehicle production for measurement tasks such as vehicle chassis, body assembly and vehicle interiors, are often quite cumbersome and time consuming. A typical example is vehicle body measurement, which often involves components from a variety of suppliers, in the vain hope that everything will fit together first time.
Below: The latest MetraSCAN hand-held scanning system
T
he HandyProbe optical CMM is a handheld, wireless and arm-free measuring system, comprising a handheld probe that can measure to a high degree of accuracy in any environment. The system incorporates TRUaccuracy technology – the system monitors the measuring environment and dynamically tracks the object being measured. This makes the system impervious to the environment, so it performs with equal speed and accuracy literally anywhere.
An addition to the HandyProbe is the handheld MetraScan, which provides high speed, high accuracy 3D laser scanning of surfaces. MetraScan also works in any environment, making it ideal for shop floor use. By scanning surfaces extremely quickly, the user can easily compare assemblies directly back to original CAD data, or indeed to master scan data. Being completely handheld, MetraScan offers users a high degree of flexibility, as it can scan large volumes with consummate ease.
The system has been deployed for investigating the build quality of several train vehicles, both externally and internally. Scan data from partially assembled vehicles was compared to nominal CAD data to see how the structure had deformed during assembly. For the first time ever, engineers were able to quantify distortion of the train body and to see graphically how that distortion affected vehicle quality.
Other applications include geometry checks on vehicle bogeys, seat installations, gap and flush on vehicle interiors, window seals, etc.
Measurement Solutions will be demonstrating the systems on booth H125 at Railtex. The company also offers on-site demonstrations and will benchmark
the system using
customers’ parts if required. FOR MORE INFORMATION
