This paper presents a method to determine the axial and radial load distribution as the moment generated in a V-band
clamp and is validated experimentally and with a finite element analysis. The method comprises a slotted flange distinguished by having three different profiles for different levels of load symmetrically divided among eight sectors.
Each sector is characterised and calibrated. The load cell is analysed in finite element Abaqus software to predict and corroborate the system. In the experimental test, the axial and radial loads are measured by strain gauges for each sector and the total axial load is validated by three button sensors. Tests on the V-band clamp were successfully carried out indicating a non-uniform distribution of axial and radial loads, with three highlights related to the existing papers: improved results for axial loads, new results for radial loads and an analysis of the moment and its direction, being consistent with finite element studies.
