Abstract

The article presents technical solutions for the creation of deforming devices with a power drive made of a material with a shape memory effect. As an example, the designs of a press, a press stamp, and a hardness tester, in which new designs of multilink power drives are used, are considered. A method of designing a universal multilink power drive is proposed, the power elements of which are made of thermally thin material with a shape memory effect. The analysis of thermal processes in power elements of various shapes and geometric sizes and using different methods of their heating (current transmission heating, convective and radiant heat exchange) is given, which makes it possible to determine the efficiency of the devices being created. The technological and operational properties of thermally thin power elements of a multilink power drive are investigated. To determine their qualitative and quantitative indicators, a measuring stand has been created that allows recording the current strength, temperature change, displacement, and developed forces on a single time scale. On the basis of the calculations performed, a line of universal power drives with a developed deformation force of 500–10 000 N and a displacement of 1.0–8.0 mm was created; the results of their testing and use in existing models of deforming devices are presented.
