چکیده

In this paper, a study was carried out to investigate the surface roughness and material removal rate of low carbon NiTi shape memory alloy (SMA) machined by Wire Electro Spark Erosion (WESE) technique. Experiments are designed considering three parameters viz, spark ON time (SON), OFF (SOFF), voltage (V) at levels each. The increased from 2.1686 μm 2.6869 with an increase in both SON time, SOFF decrease voltage. 1.272 mm3/min 1.616 but varying effect observed were varied. analysis revealed that intensity duration had unswerving relation concentration microcracks micropores. More micropores seen combination = 120 µs, 30 V. 2 could be minimised using appropriate parameter setting. Therefore, removal, is recommended machine 110μs – 55μs 30v (SON V respectively), achieve better minimal damage.

Optimal Design of Shape Memory Alloy Wire Bundle Actuators

This research studied the optimal design of Shape Memory Alloy (SMA) muscle wire bundle actuators. Current literature describes the use of multiple muscle wires placed in parallel to increase the lifting capabilities of an SMA actuator, which however, is limited to wires of like-diameter. A constrained optimization problem was formulated, with constraints on the maximum number of wires, voltage...
