This article deals with the damage detection at the suspension of a railway freight waggon and reveals that the measured accelerations change with the damage in a characteristic way. The authors sh...

2020 23rd International Microwave and Radar Conference (MIKON).
Radar technology in the mm-wave frequency band is a promising approach for the detection of birds and bats at wind turbine installations in order to reduce fatalities either by direct collision of the animals with the rotor blades or through barotrau

Seit der Mensch sesshaft wurde, greift er in den Wasserhaushalt ein. Am Beispiel des Lechs, der bis ins 20. Jahrhundert als letzter Wildfluss der nördlichen Alpen galt, skizziert Friedmann zunächst die natur- und kulturgeographische Ausgangssituati

Structural Health Monitoring. 17:815-822
Structural health monitoring of wind turbine blades is challenging due to its large dimensions, as well as the complex and heterogeneous material system. In this article, we will introduce a radically new structural health monitoring approach that us

Structural Health Monitoring (SHM) systems for structural parts of freight wagons are subject to special conditions. An important task of those systems is to detect damage to the leaf springs of the wagons. In such a case, the damaged wagons must be

Main task of an SHM system on a wind turbine is to detect defective developments at an early stage on all load-bearing components such as rotor blades or tower. This prevents damage and allows repair measures to be planned in time. But a vibrationbas

In wind energy, the objective of fleet monitoring is to achieve the best possible energy yield and to early detect upcoming defects or not optimally adjusted turbines. If a vibration-based SHM system like SHM.Blade® is installed on all turbines of a

SHM is a growing field for new and ageing infrastructure around the globe. Not least, since revenues for industry, operators and insurances are becoming increasingly obvious. Offshore wind turbines (OWT) represent an ideal application case – Being
