Abstract

The study about a variable geometry truss is presented. The first step is a kinematic design and later an analysis using the MSC/Adams code. Then, the finite-element method with the MSC/Nastran code was used to develop a variable mathematical model to characterize its mechanical behaviour. An explanation is given of the solution selected to analyse the most complex joints. A series of measurements were carried out using different experimental techniques. The aim of photogrammetry tests is to study clearance effect in the joints. On the other hand, measurements of the stiffness were carried out to introduce these data in the finite-element model and thus characterize the accurate position of the structure.
