基于OPTISTRUCT平台的某飞机摇臂结构优化设计

Structure Optimization for Crank Based on OPTIST RUCT

结构优化设计是将结构重量、结构强度和材料布局等进行最优统筹规划的手段。该文基于Altair Optistruct软件平台,针对一种常见的飞机襟翼摇臂结构,首先,使用拓扑优化方法获得摇臂的初步结构形式;其次,通过尺寸优化方法得到摇臂结构的大致尺寸;最后,综合考虑强度、刚度、加工工艺及材料利用率等因素,确定出优化后的摇臂结构。

Structure optimization is an overall plan method that balances structure weight,structure strength and material distribution to the greatest extent.In this document,we firstly execute topological optimization method on a usual aircraft's flap crank to acquired the primary form of structure based upon Altair Optistruct,then use size optimization method to obtain the approximate size of crank,and lastly get an optimal crank by considering strength ,stiffness,technics and utilization of material.
