摘要
Abstract
An optimization design method for the geometrical parameters of wheel spoke, consisting of I-shaped cross section and wheel flange, was proposed for flywheels. A flywheel with 68Nms nominal angular momentum was taken as an example. In the optimization, the constraint conditions were the moment of inertia of the wheel body, geometrical parameters and strength, stiffness and mass of the flywheel. And the goal of the optimization was to minimize the acceleration transmissibility (defined as the acceleration rate) of the rim output response to the input of base-excitation. The finite element method was used to develop the model and the Multi-Island Genetic Algorithm (MIGA) was employed to carry out the multi-disciplinary design optimization. It is demonstrated that by using the proposed method, the acceleration transmissibility is reduced significantly on the premise of meeting the design requirements. The proposed method is able to improve the design efficiency for spacecraft flywheels.关键词
