Testing and fatigue strength wind energy plants

In light of the increasing size and complexity of plants, criteria, such as operational reliability and life span, become more and more important. With the know-how of approx. 300 development and test engineers and its unique test infrastructure, IABG is a competent partner for the verification of complex technical systems, also in the area of wind energy plants. Our services within the sector of testing and qualification of wind energy systems comprise the testing of materials and components, all the way to complete systems:

Materials testing & method development

  • Consideration of on-site manufacturing conditions, material discontinuities and stress characteristics for material samples
  • Assessment of technological influence factors
  • Damage calculation with fracture-mechanical methods
  • Integration into the CAE process
  • Cost saving by up-scaling results to component level

Component testing

  • Availability of real loads on individual components and/or the tower mount
  • Real interface conditions and interaction, also concerning mounting systems
  • Component-related testing concepts
  • Avoiding over- and/or under-sizing

System verification

  • Interaction of all hard- and software components (mechanical / control, “hardware into the loop”)
  • Network integration and noise
  • Verification of models, simulations and component tests

Test stand construction and testing

We project and implement test facilities at the highest of technical levels. The salient features of our test facilities are safe operation, easy handling, flexible application options, cost-effective maintenance and problem-specific expandability. This is how we ensure cost-efficiency and future viability.

Our services

  • Customer support and consultation, e.g., on the preparation of specifications, conceptual design and when implementing test stands
  • Customised / tailor-made special purpose test stands
  • Implementation of large-scale component test stands as general contractor

Testing and Fatigue Strength

The headquarter in Ottobrunn houses a covered test hall (5,000 m2) with a modern infrastructure, central supply of hydraulic fluid, compressed air and cooling water as well as safety facilities (e.g. works fire brigade). Our standard and special test benches are used to examine, test and qualify complete vehicles, functional units and individual parts and components. We examine the dimensions and design, the materials used as well as their behaviour when exposed to defined loads. Furthermore, we develop innovative test equipment.

We would be glad to personally advise you – prior to the start of the project, during the complete production cycle and when it comes to specific problems.

Materials Testing and Damage Analysis

We offer our customers universal, competent and prompt support in failure analysis, materials testing and the development of remedial measures for further product and process development.

In the field of  failure analysis we are VDI 3822-compliant for systematic methods. We implement complementary testing methods in agreement with our clients both in our fully equipped laboratory and on-site. Our experts draft failure evaluation reports based on the following aspects:

  • Determination of failure mechanisms
  • Deduction of possible failure causes
  • Definition of remedial measures
  • Active failure prevention

Standardised work processes permit us to quickly and flexibly develop an examination concept tailored to your request. Our statement of work gives you an initial insight.

The materials we examine range from metals to non-metals, from synthetics to composite materials and material combinations. Our expertise covers the evaluation of different production and manufacturing processes – including additive manufactoring.

We use the following methods to characterise systems, components, materials and defects:

We advise you on matters concerning series production and development and respond in depth to specific questions. More experts are also available to provide aggregate services for design, layout, simulations, functional tests and environmental simulation.

Contact us and we will gladly bundle up a combined service package for you.
