摘要
飞机在空中的飞行状态对于航空飞行的安全有着不可忽视的影响。根据曲面梯形机翼飞机的特点,运用UG NX软件对其进行了三维建模,并导入至ANSYS Workbench中,从而进行有限元静力学仿真研究。探讨了不同材料的曲面梯形机翼形状的飞机在飞行过程中的总变形图和应力分布图。结合总变形图和应力分布图,仿真结果表明,机翼的部分有较大的变形,最危险的地方存在于机翼的连接处和机翼边缘,故此需要对其材料进行调整或者优化飞机的结构,优化后的结构能够满足飞机飞行的要求。并进一步对结构钢材料和铝合金材料的模型进行了对比,发现采用结构钢的飞机机翼应变分布的更合理,满足飞行的作业要求。
The flight state of aircraft in the air has a significant impact on the safety of aviation flight.According to the characteristics of the curved trapezoidal wing aircraft,this paper uses UGNX software to carry out 3D modeling,imports the corresponding model in ANSYS Workbench module,and carries out finite element statics simulation analysis with ANSYS software.In this paper,the total deformation and stress distribution of curved trapezoidal airfoil of different materials are discussed.Combined with the total deformation map and stress distribution map,the simulation results show that the wing part has a large deformation,the most dangerous place exists in the joint of the wing and the edge of the wing,so it is necessary to adjust the material or optimize the structure of the aircraft,the optimized structure can meet the requirements of aircraft flight.By comparing the models of structural steel and aluminum alloy,it is found that the strain distribution of aircraft wings using structural steel is more reasonable,which can meet the requirements of flight operation.This study is of great significance to simplify aircraft structural design and improve design efficiency.
