Calculation of constructive parameters of SMA damper

Abstract

Shape memory alloy (SMA) based damper device is presented in this paper. The device is composed of pre-tensioned SMA wires and two pre-compressed springs which supply tension of the wires. Pre-tensioned SMA wires provide the system reliability and good damping properties. After removing the external load pre-compressed springs provide recovery of the device to its original shape. The calculation method of strength and constructive parameters of the damping device is offered. The internal force, the maximal displacement value and the pre-tension magnitude of SMA wires are defined. The maximum allowable internal force of the wires is determined.
