摘要
Abstract
The ribs are used to keep the shap of the wing and only carry little of the global bend loads acting on the wing. However, the weight of ribs makes up significant fractions of the total weight of the wing box, about 8% to 12%. So it is very necessary to use some optimization method to reduce the weight of the ribs. An topology optimization method named globalization of stress constraints, which is developed on the MSC. PATRAN, is used to optimize the ribs of the wing for the first time. An engineering prediction method is applied for the primary design of the rib and fast calculation of the mass of the rib. The studies indicate that the rib weight based on the optimal topology configuration that is satisfied with the stability requirements can be reduced apparently.关键词
