چکیده

A rotational joint is introduced for use in shape morphing or deployable space truss structures. The joint is a chain mechanism comprising up to six pivoted linkages that provide a compact mechanism for the connection of up to six structures at a node. The total number of degrees of freedom for a constrained joint mechanism with six links is found. A closed chain model is then used to determine the angle between the adjacent links as the structure is changed during shape morphing. The limiting pivot rotation angle is established by physical interference and is determined for a model problem. (Some figures in this article are in colour only in the electronic version)

Shape morphing hinged truss structures

Truss structures are widely used for the support of structural loads in applications where minimum mass solutions are required. Their nodes are normally constructed to resist rotation to maximize their stiffness under load. A multi-link node concept has recently been proposed that permits independent rotation of tetrahedral trusses linked by such a joint. High authority shape morphing truss str...

EFFICIENT SIMULATION FOR OPTIMIZATION OF TOPOLOGY, SHAPE AND SIZE OF MODULAR TRUSS STRUCTURES

The prevalent strategy in the topology optimization phase is to select a subset of members existing in an excessively connected truss, called Ground Structure, such that the overall weight or cost is minimized. Although finding a good topology significantly reduces the overall cost, excessive growth of the size of topology space combined with existence of varied types of design variables challe...

Actuator placement optimization in a Kagome based high authority shape morphing structure

An optimization protocol for a high authority shape morphing plate is described. The shape morphing design incorporates an active back-plane comprising a Kagome truss, capable of changing the shape of a solid face, connected to the back-plane by means of a tetrahedral truss core. Several members of the Kagome truss are replaced by actuators, enabling the structure to deform. The trusses to be r...

Morphing Structures Technology and Its Application to Flight Control

The common goal of all aerospace advancements is safe, efficient air transportation. Current methods for achieving directional stability—control surfaces such as flaps and ailerons—are heavy and inefficient. If these bulky mechanisms were replaced with an ultra-lightweight morphing structure, efficiency could be increased by cutting drag and weight. In this project, an active truss structure ha...
