Systems Approach to Modeling Shape Memory Actuators

X. Lu, V. Hayward, D. Grant

A mathematical model for shape memory actuators has been developed. It accounts for thermal, material (chemical and mechanical), and kinematic properties as separate attributes, which once interconnected account for the input-output properties of this type of actuator. A software package has been written which is sufficiently flexible to be used as (a) a simulator to study controllers, (b) a design tool to find the dimensions of a given actuator with given constraints. Work is in progress to develop an engineering model suitable for control design.
