Embedded composite-steel welded inserts

17-07-2016 Wieringerwerf
Early this year a small joint industry project was conducted on the evaluation of embedded composite-steel insert connections. These innovative 'hybrid' connections consist of a steel plate, potentially with spikes added for additional locking, embedded in a composite. A potential benefit of this configuration is that e.g. composite ship skin panels can be joined using standard welding. The goal of this evaluation project was to investigate the influence of welding-induced heat on the composite-steel connection.

WMC on track!

15-04-2016 Wieringerwerf
WMC conducted several tests for voestalpine Railpro in corporation with DEKRA Rail on insulated Electrical Separation joints for rail bars. First an ES-joint was tensile loaded in length direction (statically up to 160 tonnes and dynamically up to 80 tonnes) while measuring the joint separation distance and monitoring the isolation disc between the rail bars. Secondly an ES-joint was fatigue loaded in 4-point bending up to 10 million cycles. During the 4-point bending fatigue test, the joint was periodically sprayed with water and the electrical resistance over the joint was measured.

Flapwise fatigue test on the EWT29 blade at Knowledge Centre WMC

07-04-2016 Wieringerwerf
Knowledge Centre WMC performed the full scale testing program for the certification of the EWT29 rotor blade for wind turbine manufacturer EWT. As part of the blade test program, the flapwise fatigue test was performed at the first flapwise resonance frequency of the blade (see video). Both the range and average of the bending moment distribution are controlled during the test by using two hydraulic actuators. The rotor blade is used in the EWT DW61 direct drive wind turbine with a rotor diameter of 61 m For more information about this wind turbine please visit the website from EWT.
