【Abstract】 To decrease the effect of the wind forces, the feed cabin of the largest radio telescope is designed as a half ball. By the static analysis method for the nonlinear finite elements, the position and posture of the feed cabin, the curve equation, extension forces and lengths of the six cables are studied. To obtain the only solution to the nonlinear equation system, an optimization method is used.更多还原
