Abstract: | The stowing and deploying experiment was conducted for three 700 mm long thin-walled tubes, and the structural behavior characteristics
parameters were measured clearly, including strain, deformation and wrapping moment. 3D finite element models (FEM) were built
subsequently and explicit dynamic method was used to simulate the stowing and deploying of the lenticular carbon fiber reinforced
polymer (CFRP) thin-walled tubular space boom, which was designed as four-ply (45°/ − 45°/45°/ − 45°) lay-up. The stress and
energy during the wrapping process were got and compared with different wrapping angular velocity, the reasonable wrapping
angular velocity and effective method were conformed, and structural behavior characteristics were obtained. The results were
compared and discussed as well, and the results show that the numerical results by 0.628 rad/s velocity agree well with the
measured values. In this paper, the numerical procedure and experimental results are valuable to the optimization design of
CFRP thin-walled tubular space boom and future research. |
