Kagome plate structures for actuation

Single member actuation of kagome lattice structures

“…Recent studies have shown the two-dimensional kagome lattice, shown in Figure 1, to be a prime candidate to form the backbone of active structures [Santos e Lucato et al 2004;Hutchinson et al 2003;Symons et al 2005a;2005b]. If linear actuators replace some members of the truss, significant global macroscopic shape changes can be achieved with a relatively small number of actuators.…”

“…The paper will focus on the structural response of the truss rather than methods of actuation; possible actuators are described in [Santos e Lucato et al 2004;Symons et al 2005a;2005b]. Hutchinson et al [2003] has shown that the planar kagome lattice can be actuated with minimal internal resistance while maintaining overall stiffness. The rigid-jointed planar kagome lattice exhibits high passive stiffness, while having a low actuation resistance.…”

Optimal Locations of Dampers/Actuators in Vibration Control of a Truss-Cored Sandwich Plate

“…The truss-core is a tetrahedral truss that lies in between the two faces (see figure 1). The ancient planar Kagome basket weave pattern truss is simultaneously static determinacy and stiff [12]. This feature of the planar Kagome truss enables its truss rods to be actuated in order to achieve arbitrary inplane nodal displacements with minimal internal resistance.…”

“…They are statically determinate yet stiff, see Fig. 11 and Hutchinson et al (2003).They can be actuated into relatively intricate surface shapes. The structure consists of a face sheet or skin with a Kagome activated backplane truss.…”
