Abstract
The present application relates to a superelastic SMA structure, with enhanced power density and compressive stability, comprising two or more connected plate sections to form an overall substantially closed perimeter, wherein the structure comprises an opening positioned in the centre of the structure, and wherein the connected plate sections are dimensioned with a circular symmetry to allow a stacking assembly, and wherein each section includes an array of hollow perforated cells formed between one or more thin vertical walls of a thickness within a predefined range of values, and wherein at least one perforated cell defines a fluid passageway within a predefined range of hydraulic diameter values.
Claims16
A superelastic SMA structure, comprising:
- an opening positioned in the centre of the structure;
- two or more connectable plate sections forming a connected plate section with a substantially closed perimeter, the two or more connectable plate sections being dimensioned with a circular symmetry to allow a stacking assembly of a plurality of connected plate sections that includes the connected plate section, the circular symmetry being relative to the opening;
- wherein each of the two or more connectable plate sections includes an array of hollow perforated cells formed across a surface of the two or more connectable plate sections, the array of hollow perforated cells being separated by one or more vertical walls of a thickness within a predefined range of values, the thickness of the one or more vertical walls being a dimension between adjacent cells of the array of hollow perforated cells;
- and
- wherein at least one perforated cell of the array of hollow perforated cells defines a fluid passageway within a predefined range of hydraulic diameter values.
