Method for improving robustness of cable dome structure based on quality constraint
The invention discloses a method for improving the robustness of a cable dome structure based on quality constraint, and the method comprises the steps: (1) obtaining a to-be-optimized cable dome structure model, extracting a single profile model, and obtaining shape features; (2) determining a search space of each shape feature according to the value of each shape feature by taking the shape feature as an optimization variable; and (3) searching a single-truss profile model with the optimal robustness by adopting a global optimization algorithm by taking the condition that the single-truss mass of the optimized cable dome structure model does not exceed the single-truss mass of the to-be-optimized cable dome structure model as a constraint condition and taking the optimal overall robustness of the cable dome structure as an optimization target. Aiming at the characteristics of the cable dome structure, under the precondition of quality constraint, the overall robustness of the cable dome structure is calculated by combining shape characteristic acquisition and finite element analysis, and a global optimization algorithm is adopted to optimize the shape characteristics of a cable dome structure model, the dead weight of the cable dome structure and the overall robustness.
