Analyzing and modeling performance of a new SMA actuator-based barrier structure

摘要: This paper presents how a SMA spring-based barrier structure actually does work. An experimental model, consisting in rather small barrier, was built. The spring is activated by applying different values of electric current and the arm charged with concentrated weights. To collect data, DAS acquisition system used. Finally, some theoretical aspects regarding dynamics motion were presented. proposed dynamical study made dependent generalized coordinates. For obvious reasons, mass neglected, but all rest moving parts actuator taken into consideration. ends authors' conclusions concerning novelty originality their
