面向周期性的变刚度层合板轨迹规划及屈曲特性
Trajectory planning and buckling characteristics of periodic variable stiffness laminated plates
摘要
Abstract
In order to improve the load-bearing capacity of composite laminated structures,the compression buckling properties of the laminates were studied.First,in order to improve the designability of linear function traj-ectories,this paper proposes a new periodic linear fiber trajectory function mathematical model based on the charac-teristics of trigonometric function curves;secondly,Python/ABAQUS is used to conduct secondary development modeling of composite laminates;finally,the classic comparative buckling analysis of constant stiffness and new var-iable stiffness laminates revealed the response mechanism of the buckling performance of variable stiffness laminates to the curve trajectory starting and ending angles and period parameters.The results show that when the T0 and T1 values of the variable angle trajectory are in the range of[30°,60°],the first-order buckling load is significantly higher than the classic constant-stiffness laminate,and is 21.41%higher than the optimal constant-stiffness lami-nate buckling load.And by controlling the value of period n,the first-order buckling load of the laminate can be further increased,thereby improving stability.关键词
