Abstract
The paper deals with Shape memory alloy (SMA) spring analysis and its possibility for usage as actuator for in-pipe machine. In the paper the inner structure of SMA is introduced. Further, the experimental analysis of SMA contractor and expander was done. From the experiments was found that SMA spring has several disadvantages like long time of cooling and high electric power consumption. Using SMA spring as actuator for in-pipe machine has been obtained average velocity of in-pipe machine roughly 2 mm/min. Advantage of SMA spring as actuator is its good expansibility.

Abstract
This paper deals w ith actuators based on shape memory alloys. The testing device has been developed for experimental verification of shape memory alloy actuator testing. Static characteristic shows the hysteresis of this material. Also dynamic properties have been explored through the step response characteristic. Application of the material as actuator in engineering system is shown. [ABSTRACT FROM AUTHOR]
