SMA Actuator with Active Clamp

The paper deals with modeling and simulation of the Shape Memory Alloy (SMA) actuator for mechatronic systems. The thermal actuator made of Nickel–Titanium (NiTi) wire and new active clamp are heated by electric resistance heating and naturally air-cooled. The paper addresses FEM electro thermal simulation of NiTi actuator with special shape of clamp with active heating and shows design of new connection with improved thermal features.
