- 摘要:
- 目前飞行器的结构大多采用折叠翼舵结构的设计,目的是让空间更节省,运输更加方便。而建立合理的折叠翼舵结构模型进行动力学分析和优化,对于改进结构减小振动危害和提高飞行器的安全性尤为重要。针对折叠翼舵结构进行ANSYS有限元建模和模态分析,为后续折叠翼舵结构动力学分析夯实基础。由于该结构一个方向的尺度(厚度)远小于其他方向的尺度,因此忽略沿厚度方向的应力,采用壳单元进行建模。仿真结果表明,通过对数据、云图、动画等的分析,能更直接更方便地分析模型的各阶模态的特点。
- Abstract:
- At present, the structure of aircraft mostly adopts the design of folding wing rudder structure, in order to save space and facilitate transportation. The establishment of a reasonable model of folding wing rudder structure for dynamic analysis and optimization is particularly important for improving the structure, reducing vibration hazards and improving the safety of aircraft. The finite element modeling and modal analysis of folding wing and rudder structure are carried out by ANSYS, which lays a solid foundation for the subsequent dynamic analysis of folding wing and rudder structure. Because the scale(thickness)of the structure in one direction is much smaller than that in other directions, the stress along the thickness direction is ignored and the shell element is used for modeling. The simulation results show that the characteristics of each mode of the model can be analyzed more directly and conveniently through the analysis of data, cloud images and animation.
