The present paper is dedicated to the analysis of deployable tensegrity columns. The main aim of this work is to present a technique, developed by combining the finite element (FE) analysis and the multibody dynamics (MBD) simulation, which enables precise and reliable simulations of deployable structures. While the finite element model of the column provides information on structural behavior in the deployed state, the dynamical modeling allows to analyze various deployment scenarios, choose active cables for the deployment and for the self-stress application, and to control distributions of internal forces during the assembly process. An example of a deployable column based on a popular tensegrity module – a 3-strut simplex – is presented. By analyzing the proposed column with the use of the developed method it is proven that the technique is suitable for complex simulations of deployable systems.
