Abstract

In this work, a program was developed to calculate the bolted joint stiffness, using the DOBROVOLSKI method, the SHIGLEY method, and under an analytical model. In addition, the behavior of the trajectory of the compression cone generated in a bolted joint was analyzed for different sizes of bolts from 0.190 to 0.375 inches in diameter, preloading from 2 to 4 flanges of 0.20 inches thick, that is, varying the grip length. of the bolted joint, using SOLIDWORKS and ANSYS to make a comparative analysis in the solution by both programs. The compression path through the joint is important as it helps us to understand the behavior of the joint stiffness to achieve a higher degree of safety and quality when designing a bolted joint for the aeronautical sector. The results show that it is possible to quantitatively determine the load distribution from a force applied to the joint, as well as its distribution between the bolt and the fastened elements, in addition to providing the force required to separate the joint. From the simulations in ANSYS and SOLIDWORK, it can be concluded that the difference in stiffness of the bolted joints in the compressive zone is a maximum of 10%. This will not represent a significant variation in the calculation of the elastic constant of the bolted joint. Finally, the results show that the analytical model obtained from the different simulations is reliable since there is an elastic constant of the joint of 0.165 (0.375 inches DIA-4 flanges), while 0.17 in ANSYS, and 0.16 in SOLIDWORKS, less than 2% variation.
