Abstract:
An improved method for the calculation of actual operating force on every bolt in the bolted joint has been developed. It is founded on the usage of so called “elasticity” and “stiffness” matrices of joined structures. Elasticity matrices have to be calculated separately for each part of joined structures and for every bolt position in the structure. The method is generalized and has been tested numerically and experimentally at different external structure loads and at different relative orientation of joined structures. Numerical results show considerable differences with respect to the results obtained from applying the very simplified theory. Experimental results confirm those deviations and show good agreement with numerical results.
