Laboratory scale test for accelerated test of flanges and bolts. Measurement of static and dynamic relaxation of bolts. Funded by Parkwind and led by OnderzoeksCentrum voor de Aanwending van Staal, an advanced, market-oriented research centre providing steel and metal-based products, services and solutions, to metal processing companies worldwide.
Monitor data on bolted connections from our windfarms is a slow process. With our and OCAS R&D teams, we are running an accelerated fatigue test on relaxation of bolts to help us improve future design.
At OCAS, the project is using a "CRONOS" test machine for accelerated fatigue testing of flanges and bolts where 2 million stress cycles can be performed in less than a week.
