Research And Construction Simulation Of The Flat Tensegrity Grid Structure

This paper primarily mentions the background and the conditions of the development of the space structure; simply introduced different kind space structures applications; looked back the development history and the mechanics characteristic of the tensegrity system. Followed the phenomenon and the arguments of the strut continuous and discontinuous, the paper put forward the conception of the tensegrity and tensegrity and analyzed the merit and shortcoming of the two kinds of system. A novel joint-assemble joints was detailed introduced.For the tensegrity system reasonable prestress value and reasonable method,proper sequence for applying the tension was decided the shape of the structure and the safety of construction and working state. By means of the nonlinear finite element theory and computer simulations, this paper gave out some method of applying the tension for the flat tensegrity gride structure and compared the different result of each kind of the method. Then the principle of optimization design for tension order was putted forward. The paper also analyzed the choice of tensile cable and the initial tension force control.The construction process and mechanics characteristic of a flat tensegrity grid structure assembled by joint-assemble joints was analyzed in detail. It could conclude that if the big block was divided reasonably block assembled method of construction for the flat tensegrity grid structure was feasible. Then other forms of tensegrity structure assembled by joint-assemble joints and its outlook was simply brought forward.At the end of the paper some conclusions were summarized and the problems that should be studied further were putted forward.
