Optimization of bolted joints connecting honeycomb panels

Optimization of bolted joints connecting honeycomb panels
Optimization of bolted joints connecting honeycomb panels
The paper examines the range of issues associated with
the optimization of bolted joint connections between
honeycomb panels, representative of spacecraft structures.
The first part of a large body of work, involving the
application of experimental, finite element and analytical
methods, has been carried out.
A procedure has been developed to maximize the load
carrying capability per unit mass of shear joints by
optimizing the balance between the number of bolts and
the size of the bolts used in the joint system.
The finite element method has been used with the primary
aim of analyzing the stress levels experienced by the
connection strips of bolted joints under different loading
conditions and to investigate the effect of modifying
various design parameters (e.g. connection strip thickness
and number of bolts).
Lastly, a test campaign has been carried out to asses the
performance of honeycomb panel inserts subjected to out
of plane loads in “T” joint applications. Test results
obtained from two different insert systems are compared
together with static strength capability results obtained
from an analytical model.

Abstract

The paper examines the range of issues associated with
the optimization of bolted joint connections between
honeycomb panels, representative of spacecraft structures.
The first part of a large body of work, involving the
application of experimental, finite element and analytical
methods, has been carried out.
A procedure has been developed to maximize the load
carrying capability per unit mass of shear joints by
optimizing the balance between the number of bolts and
the size of the bolts used in the joint system.
The finite element method has been used with the primary
aim of analyzing the stress levels experienced by the
connection strips of bolted joints under different loading
conditions and to investigate the effect of modifying
various design parameters (e.g. connection strip thickness
and number of bolts).
Lastly, a test campaign has been carried out to asses the
performance of honeycomb panel inserts subjected to out
of plane loads in “T” joint applications. Test results
obtained from two different insert systems are compared
together with static strength capability results obtained
from an analytical model.
