Tensegrity structures are spatial systems that are composed of tension and compression components in a selfequilibrated prestress stable state. Although tensegrity systems were first introduced in 1950s, few examples have been used for civil engineering purposes. In this paper, tensegrity-ring modules are used for a deployable pedestrian bridge. Ring modules belong to a special family of tenseg...
in this paper coupled nonlinear equations of motion of a suspended cable with time dependent tension and velocity are derived by using hamilton’s principal. a modal analysis for a stationary sagged cable is initially carried out in order to identify the dynamic system. the natural solution is directed to compute the natural frequencies and mode shapes of the free vibration of a suspended cable....
Modeling and Wrench feasible workspace analysis of a spatial cable suspended robots is presented. A six-cable spatial cable robot is used the same as Stewart robots. Due to slow motion of the robot we suppose the motion as pseudostatic and kinetostatic modeling is performed. Various workspaces are defined and the results of simulation are presented on the basis of various workspaces and app...
Carbon Fiber Reinforced Polymer (CFRP) has advantageous characteristics such as lightweight, high strength, corrosion and fatigue resistance, low creep, damping, etc. It is suitable to be used in bridge structures cables, which can effectively solve the problems of easy rusting, heavyweight, tensile performance steel cables. This paper firstly illustrates properties CFRP lamella compared with r...
The wall of hollow organs of vertebrates is a unique structure able to generate active tension and maintain a nearly constant passive stiffness over a large volume range. These properties are predominantly attributable to the smooth muscle cells that line the organ wall. Although smooth muscle is known to possess plasticity (i.e., the ability to adapt to large changes in cell length through str...
This paper presents the formulation of a finite element enclosing specific internal mechanical equilibrium in order to model cable-based structures dynamics conditions. It is based on concept macro which allows embedding complex systems solved inside boundaries. A significant advantage allow an easy implementation within classical commercial codes. The proposed describes cable interacting with ...
This paper addresses the cable tension distributions of a cable-driven parallel robot with non-negligible cable mass for large dimension mechanisms. A well-known model which describes the profile of a cable under the action of its own weight allows us to take the cable sags into account. In addition, an approach to computing the cable tensions is presented, in which there are two major steps to...
Land models are valuable tools to understand the dynamics of global carbon (C) cycle. Various models have been developed and used for predictions of future C dynamics but uncertainties still exist. Diagnosing the models’ behaviors in terms of structures can help to narrow down the uncertainties in prediction of C dynamics. In this study three widely used land surface models, namely CSIRO’s Atmo...
