摘要：

Composite corrugated plates are widely used in wall webs of aircraft wings and their buckling reliability under shear loading is a key factor to be considered during the design of corrugated plates. Based on their equivalent models with flexural and tensional rigidities, a computation method for critical shear buckling loads of composite corrugated plates was derived by utilizing Ritz method and the principle of minimum potential energy. The uncertainties in composite structural parameters and external load were fully considered and quantified with interval vectors. By means of the vertex solution theorem, the response ranges of buckling factors were predicted and the interval analysis method of buckling reliability under shear loading was proposed. The interval possible level was adopted to describe the reliability of shear buckling. An interval reliability optimization model containing effects of parametric uncertainties was proposed for composite corrugated plates. Numerical examples indicated that the results with the proposed method and those with FEM agree well and the optimal results verifies the effectiveness of the proposed interval reliability optimization model and algorithm. © 2016, Editorial Office of Journal of Vibration and Shock.
