giant magnetostrictive clamping mechanism for heavy-load and precise positioning linear inchworm motors

  this paper focuses on the development of a novel clamping principle and the mechanism that may be used to realize a linear motor capable of performing not only large thrust but also secure movement with high blocked clamping force. to verify this principle, a clamping prototype (size: /32  130 mm) is constructed and tested. it generates a clamping force of 1050 n with an initial experimental set-up, and, a clamping force up to 1525 n with a modified set-up employing a hydro-press bench clamp. the theoretical and numerical analyses are carried out and suggest that the mechanism may generate a clamping force up to 2148 n with an adequate rigid guide-way.
