Predicting and determining the contact pressure distribution in joints formed by v-band clamps

V-band clamps are utilised in a wide range of industries to connect together a pair of circular flanges, for ducts, pipes, turbocharger housings and even to form a joint between satellites and their delivery vehicle. In this paper, using a previously developed axisymmetric finite element model, the impact of contact pressure on the contact surface of the V-band clamp was studied and surface roughness measurements were used to investigate the distribution of contact pressure around the circumference of the V-band.
