The aim of this work was to analyse the options for predicting pin connections, using modern computer aided systems. These advanced methods include Special-Purpose Programs and Finite Element Analysis, which fundamentally differ in their duration and precision of results. Some of these methods allow calculation including the influence of the force and pin position, position of the stiffness centre, and stiffness of the connected parts. These conditions significantly affect the results. The evaluation of results is different in all the calculation methods. The resulting evaluation in Finite Element Analysis is a task for the designer, as well as the calculation using some Special-Purpose Programs (for example BSPOJ). Other Special-Purpose Programs (for example KISSsoft or MITCalc) evaluate the pin connection automatically. This work describes the comparison of these prediction methods for pin connections, and the evaluation of the results.
