Abstract

The driving characteristics of SMA actuators mainly include the range, force and speed of the actuator, and these driving characteristics are determined by the alloy composition and use conditions. The alloy composition and service conditions affect the stress, strain and phase transformation speed of the SMA wire during the phase transformation, and affect the driving characteristics of the SMA wire. Using the shape memory alloy seat drive element with one-way shape memory effect, two-way drive can be realized under the action of bias force. The driving characteristics of alloy wires under the action of different constant loads and bias springs with different stiffness, including the influence laws of driving displacement, driving force and response time.
