SHAPE MEMORY EFFECT IN Cu-Al-Ni SINGLE CRYSTALS AND THEIR APPLICATIONS IN LINEAR ACTUATORS
Here we report on the experimental study of the functional prop- erties of Cu-Al-Ni single crystals with the tensile shape memory effect under the conditions simulating the operation of a force el- ement in а cyclic linear actuator. Core design principles and oper- ating conditions for linear actuators with force elements made of shape memory effect functional materials are laid down. Key rela- tions between the functional material properties and actuator’s fun- damental characteristics, such as the maximum stroke, maximum developed force, and produced mechanical work are determined.
