Measuring System Turned Upside Down

Mobile Bogie Test Rig Saves Time, Space and Money
CHEMNITZ, GERMANY. Since the end of February 2013, the Augsburg municipal services have been using a new test rig for gauging their tram bogies. The distinguishing feature of this system: the BMS 09 is a mobile system for testing, maintenance and presetting of bogies for railway vehicles of various types and sizes. It only requires 3.30 x 2.50 meters of space, weighs just under four metric tons and can be installed within two hours, making it quick to implement in workshops with limited space. Thanks to these advantages, the investment costs are clearly lower than those of stationary systems.
Test rig for gauging tram bogies
The engineers and skilled workers of Voith Engineering Services GmbH, Road & Rail, Chemnitz, and AGG Anlagen- und Gerätebau GmbH, Potsdam, developed and built the system. They turned the test rig upside down, so to speak, and rotated the portal, common in the case of measuring equipment, with the load units. “BMS 09 works according to the principle of tractive force application. That allows an especially compact design,” explains Wolfgang Stumvoll, Director of Prototype Construction at Voith Engineering Services, and AGG Manager Rainer Bastian.

The patented process simulates operating loads on the bogie under defined application of force as it acts on the bogie in the installed state and at the same time measures data such as wheel vertical forces, axle parallelism, wheel disk parallelism and various Z measurements. The modularly structured system consists of hardware components and the software controlling and monitoring the test rig.

Simple measuring and assembly rigs with limited requirements can be implemented according to the modular design principle as can complex maintenance systems with automatic test rig equipment. The basic device is designed as a simple load rig and can be supplemented by other modules at the customer’s request. Test rigs with integrated track gauge changing systems, with measuring bars for determining the wheel vertical forces with various distances between the axles or with measuring prisms for determining the wheel vertical forces, automatic detection of the wheel diameter and axle parallelism, among other things, are possible.

Along with the BMS 09, which is designed for the requirements of “light rail,” Voith Engineering Services and AGG are working on the development of a test rig for “heavy rail.”
