AI Technical Summary

Benefits of technology

This patented technology describes new designs for joining two components together without causing damage or deformation during use. These improvements include improved durability by reducing stress concentration caused when there are small gaps between them, increased resistance against corrosion due to less exposed metal surface area, enhanced stability through tension relief from applied loads, ease of manufacture, efficient construction processes, and long lifespan. Overall these technical results lead to more effective connections made up of stronger metals while also being cost-effective and easy to install over longer periods of usage.

Problems solved by technology

Technological Problem addressed in this patents relates to connecting composites with strong bondings without reducing their overall effectiveness or requiring excessively long assembly times due to poor shear stress properties caused during fastener insertion into holes made through the layers. Existing methods like glues require significant pressure before joining together, while bolts may lose its grip overtime if too much torque was applied. There also exist issues related to insufficiently secure attachment between components when subjected to heavy loading conditions.

Abstract

The invention relates to a single-side rivet pulling rivet structure special for composite material interference connection and a design method thereof. The single-side rivet pulling rivet structure comprises four parts, namely an expansion bushing, a threaded core rod, a driving nut and a rivet body. The structure has the advantages that firstly, the composite material connected piece forms interference connection, so that the fatigue life of the composite material connected piece is prolonged; and secondly, the structure provides a certain pre-tightening force, so that the connecting strength of the composite material connected piece is improved. According to the connecting principle of the structure and the requirement for interference connection of composite materials, the design method for all components of the single-side rivet pulling rivet is established.
