Abstract
In order to achieve high load-carrying efficiency for fiber winding composite circular grid structure with outer skin, axial compression stability is analyzed using FEM. Parameter design program is finished using the APDL language of ANSYS. Changing law of load-to-mass ratio for circular grid structure with outer skin which is attached to helical stiffener winding angle, stiffener cross area, stiffener aspect ratio , helical stiffener couples and hoop stiffener strips has been researched utilizing the parameter design program. Axial compression experiment of specific dimension grid structure is carried out on the INSTRON1346 material fatigue strength test machine. It is shown that axial compression load-carrying capacity can be predicted using FEM; when helical stiffener winding angle is from a value between 0 degree and 40 degree, load-carrying efficiency of circular grid structure is more higher; better value for stiffener aspect ratio is in the range of 0.9-1.3.关键词
