Applied Design Optimization of Nose Landing Gear Cabin Structure of Airplane
Based on structure dynamics finite element method (FEM) numerical analysis,and optimal design methods,this paper analyzed the finite element modeling of cabin structure of nose landing gear and discussed optimal design of structural parameter.The main research work conducted included the following: Finite element discretization of structure of nose landing gear,construction of finite element model,optimal variable design,optimal design for component dimension parameter of structural low-order frequency property in numerical value technique frame,lightest structural weight under low-order frequency restriction conditions,and best geometrical stiffness structure distributing.The thesis introduced in details the structure dynamic characteristic finite element mesh adopted in performance calculation as well as the structure numerical optimal theory and discussed every detail of optical design for numerical value of intrinsic dynamic characteristics and the optimal analysis results.At the end of the paper,the author proposes the conclusion of the research.
