DESIGN OF ASSOCIATED MECHANICAL STRUCTURE OF SHAPE MEMORY ALLOY ACTUATORS

Tudor Mircea Dejeu, Dan Mandru

Abstract


   The paper is focused on highlighting the influence of the associated mechanical structure (AMS) of shape memory alloy actuators (SMAA,) on their performance in terms of generated stroke and force. In this sense, we’ve designed and developed a linear SMAA using shape memory alloy wire as an active element, and outlined the analytic results.


Key words: shape memory alloy, linear actuator, mechanical structure, prototype
