CONNECTION ARRANGEMENT AND STRUCTURE

摘要

An energy-absorbing connection arrangement with a multitude of connectors for joining two components, such as a transverse member and a circular frame element, of an aircraft fuselage. Each connector comprises a headed shaft and the shafts reach through component boreholes. On the shaft ends facing away from the heads, counter-bearings are provided. At least one of the components comprises a fiber-reinforced plastic material. A head and/or counter-bearing of at least one connector rests against at least one underlay device. The underlay device is received in a guide groove in the first component, with the guide groove commencing in the region of the boreholes. The underlay device, upon exceeding a mechanical threshold load, is slidable away from the boreholes. Energy absorption takes place along a longitudinal center axis of the guide groove as a result of hole-bearing-stress failure and/or the shearing of the fiber-reinforced plastic material component.

主权项

1. An energy-absorbing connection arrangement for joining at least two components, comprising:
a multitude of connectors, wherein each connector comprises a head with a shaft, and the shafts reach through associated boreholes in the components, counter-bearings located on ends of the shafts facing away from the heads, a first of the components comprising a fiber-reinforced plastic material and at least one further component comprising at least one of a metallic material and a fiber-reinforced plastic material, at least one of a head and a counter-bearing of at least one connector resting against at least one underlay device, the at least one underlay device being received in at least one guide groove embedded at least in the first component, and a commencement of the guide groove being in a region of the boreholes, wherein as a result of exceeding a mechanical threshold load, the at least one underlay device is slidable in a direction facing away from the boreholes, and energy absorption takes place essentially along a longitudinal center axis of the at least one guide groove.
