| Summary: | V-band clamp joints are used in a wide range of
applications to connect circular flanges, for ducts, pipes
and the turbocharger housing. Previous studies and research
on V-bands are either purely empirical or analytical
with limited applicability on the variety of V-band design
and working conditions. In this paper models of the
V-band are developed based on the classical theory of solid
mechanics and the finite element method to study the behaviour
of theV-bands under axial loading conditions. The
good agreement between results from the developed FEA
and the classical model support the suitability of the latter
to modelV-band joints with diameters greater than 110mm
under axial loading. The results from both models suggest
that the axial stiffness for thisV-band cross section reaches
a peak value for V-bands with radius of approximately 150
mmacross a wide range of coefficients of friction. Also, it is
shown that the coefficient of friction and the wedge angle
have a significant effect on the axial stiffness of V-bands. |
