Airbus Wing Integration Centre - Strong Floor, Bristol

摘要

The principal requirement was for a manoeuvrable reaction 'wall' structure, suited to the many different test arrangements required by Airbus's current and future wing designs. Test specimens are bolted to the wall via an interface structure and loads applied through hydraulic actuators fixed to the floor anchor points.The fixing points on the wall, and floor anchors, are used to connect precisely machined test components, which can be relocated to any position. A corresponding suite of construction tolerances were therefore defined for all fixing surfaces to negate the need for any local packing and ensure a consistent test setup and uniform performance.Detailed test loading was fundamental to providing an economic design. Since actual test data were either unsuitable or unavailable, representative load histograms were developed with Airbus using historic data as a guide. The peak loading, taken from simulations or previous tests, was distributed into ranges and corresponding numbers of cycles that could be used to conduct the structural design.
