Variable Geometry Truss

This paper describes a movable arch roof with external panels as an actual design of an adaptive structure using a VGT (Variable Geometry Truss) mechanism comprising an elementary truss structure with extendable members. This movable arch structure comprises several VGT units jointed in series and pin jointed at each end. It is a stable structure because its edge is restrained, but this reduces its variety of shape change. Various arch shapes can be determined by using inverse analysis to solve the structure shape from the member lengths. An actual movable roof pavilion composed of such a movable arch and an external panel was designed, and the behaviors of a movable roof and the joint mechanism of the roof elements were verified by numerical simulation and a model experiment. As a result, the performance of the proposed movable roof structure was confirmed, and the basic technology and design approach were established.

Variable Geometry Truss

Abstract In this paper some fundamental formulae are derived for tetrahedron-based variable geometry truss manipulator which is composed of a series of tetrahedrons stacked upon each other such that one link in each cell is made variable on length. Analytical model for dynamics of the manipulator is established, and expressions in numeric-symbolic form of model matrices are derived. An example is given for illustration.

Variable Geometry Truss

Abstract Homotopy continuation algorithms for solving the direct position problem of the dodecahedron variable geometry truss manipulator are proposed in this paper. The homogeneous equations and the division of groups are presented which give the lowest Bezout number. The solution procedure is given in detail. A numerical example is presented for illustration.
