Abstract:

Shape memory alloy actuators (SMAA) are attractive for lightweight construction applications such as in the fields of e-mobility and aerospace due to their properties (high actuator performance, low weight, silent operation). Used force-fit and firmly bonded connections (crimping, casting) can only be released again non-destructively to a limited extent. Combined with the complex material behavior of NiTi-SMAA, the development of standardized SMAA is limited. In this paper, a novel approach based on a form-fit connection for Nickel Titanium (NiTi) shape memory wire actuators using laser processing is presented. This paper has only presented first results of a developed form-fit connection for NiTi SMAA.
