Sustainable Transport Systems

Buses and modern trains used in local passenger transport – as well as new transport systems – make it possible to operate traffic flows in a manner which saves resources and protects the environment. Great value is placed on determining the areas in which such systems should be used, their optimum interconnections and passenger-friendly equipment but also their design.

Vibration Behaviour of Components

Measurements of the mobility of a rail vehicle wheel by impulse-type excitation with a test hammer, and measurement of the structure-borne sound. (Mobility = movability: characteristic value for the natural vibration behaviour of a component – vibration modes, stiffness, damping).

Testing of Permanent Way Components

The safety of railways depends to a large extent on the quality of the permanent way. Therefore, before components can be incorporated into the permanent way, they have to be subjected to comprehensive long-term static and dynamic pulsating loads. The vibration abatement properties of a permanent way (damping, static and dynamic stiffness) are determined on a test bed in the laboratory (hydro-pulse facility) and partly when installed in the railway networks.

Accessible Public Transport

Considering the requirements of the physically disabled in urban passenger transport is a declared aim of transport planners and transport companies. The requirements of this section of the public are analysed in workshops, and in practical tests the borderline conditions clarified. For example, it has been shown by measurements that it is not necessary to fit safety belts for the use of people in wheelchairs in urban buses.

Deformation Measurements on Railway Installations

Displacement and acceleration measurements on bridge joints to determine the static and dynamic loads as well as deformations acting on seals under an operating load (rail traffc).
