Force Finding of Tensegrity Systems Using Simulated Annealing Algorithm
Publisher: American Society of Civil Engineers
Abstract: In this paper, an optimization model for force finding of tensegrity systems with considerations of the geometrical stability condition, the unilateral property of members, and the evenness requirement of internal forces ...
Multistable Tensegrity Structures
Publisher: American Society of Civil Engineers
Abstract: Tensegrity structures have been intensively studied since they appeared in the 1950s. Their applications have been extended from architecture to other areas including aerospace structures, cell mechanics, and robotics. In ...
Tensegrity Structures with Buckling Members Explain Nonlinear Stiffening and Reversible Softening of Actin Networks
Publisher: American Society of Civil Engineers
Abstract: In this paper, a three-member tensegrity structure is used as a conceptual model for the dendritic actin network in living cells. The pre and postbuckling behavior of the tensegrity is analyzed basing on the energy method. ...
General Approach for Topology-Finding of Tensegrity Structures
Publisher: American Society of Civil Engineers
Accurate Stiffness Matrix for Nonprismatic Members
Publisher: American Society of Civil Engineers
Abstract: In this note, the transfer matrix method is adopted to deduce general expressions for the components of the stiffness matrix and equivalent node load vector of nonprismatic members, and the effect of warping is not considered. ...
Topology-Finding of Tensegrity Structures Considering Global Stability Condition
Publisher: ASCE
Abstract: This study proposes a general framework for topology-finding or topology optimization of tensegrity structures. The existing topology-finding formulation of tensegrity structures based on mixed-integer linear programming ...
Stability Conditions for General Tensegrity with Rigid Bodies
Publisher: ASCE
Abstract: This study develops stability conditions for general tensegrity regarding the three stability criteria (e.g., prestress stability, general stability, and super stability) based on an energy approach. The coupling ...
Direct Differential Kinematics of Hybrid-Chain Manipulators Including Singularity and Stability Analyses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general formulation for the differential kinematics of hybrid-chain manipulators is developed based on transformation matrices. This formulation leads to velocity and acceleration analyses, as ...
Collision-Free Path Planning of Tensegrity Structures
Publisher: American Society of Civil Engineers
Abstract: Path planning is a crucial step in shape control of tensegrity structures. A mathematical model for the path planning problem of tensegrities is proposed. Both external collision and internal collision are considered. A ...
Construction Method for Cylindrical Latticed Shells Based on Expandable Mechanisms
Publisher: American Society of Civil Engineers
Abstract: This note proposes a cost-effective construction method for large span cylindrical latticed shell structures. The method converts a latticed shell into a six-bar linkage, allowing the major part of the assembling work to ...
