Artigo:

Experimental tests with axial force and with tightening torque were performed to measure the deformation of bolted joints. From the found curves of force-deformation and torque-deformation, the experimental correlations between tightening torque and assembly force were obtained. The experimental results, together with the guideline VDI2230 [1] for calculation of bolted joints, were used to estimate the material properties and friction coefficients used at finite element numerical model. A full tridimensional model was built, where a rotational angle was applied at bolted joint and the assembly force and tightening torque were calculated. From these output results, the equations that correlate torque and force were estimated. The equations got from the numerical model are in accordance with those obtained experimentally. This way, the numerical model can be used in the future for new studies, without the necessity of new experimental tests.
