摘要：
The aim of this research was to investigate on bolted joints characterized by steel screws and aluminum nuts by means of numerical simulation. 2D and 3D CAD/FEM parametric models were developed in order to determine the preload distribution in joints with and without a Wired Threaded Inserts (WTI), so as to compare the trend of the stress distributions and the amount of load applied to each thread. The operating mechanisms and the effectiveness of a WTI were investigated in a parametric study by means of which the most important factors of the joint (materials, class, diameter, Engagement Ratio (ER), tolerance bands) were varied.
