Stability Analysis of Composite Circular Lattice Structure |
| |
| Abstract: | In order to attain composite lattice structures with high load-carrying efficiency,stability of composite circular lattice structures are analyzed by using FEM.Parametric design program is compiled with the APDL language of ANSYS.Changing law of load-to-mass ratio which is attached to thickness of inner skin,thickness of outer skin,winding angle of inner skin and winding angle of outer skin is researched by utilizing the design program.As a result,when winding angles of inner skin and outer skin are equal t... |
