The Smart Stick adaptive structure

Abstract

This paper describes the smart stick adaptive structure driving mechanism and its operation since the insertion of the tubular actuators. Inserting single tubular element between rigid links, which are elastically hinged, the mechanical structure exhibits compliant nature. The processes of the minitube insertion in between the links elastically deforming it and its interaction with link in con-tact when pressurized are modelled and simulated. The experimental research conducted using optical test rig with the aim to determine pressure – displacement function of the structure proved the validity of the developed computa-tional model. The fact makes it possible simulation and analysis of further expansion due to the preload of the in-vestigated system using an external source of pressure.
