摘要:

针对B737 系列的飞机子午线轮胎H40×14.5-19,在有限元软件ANSYS 中建立了轮胎的胎冠、帘布、胎肩等9 种不同的结构层。考虑了轮胎的三重非线性(材料非线性、几何非线性、接触非线性)以及轮胎与轮辋由于长期使用产生的粘合对轮胎分解的影响,利用pilot节点法模拟了拆胎机不同形状压盘的压胎过程。结果表明当压盘β角为40°时袁轮胎分解效果最好。该模型对轮胎分解机结构设计、压盘的优化提供了依据。

Abstract:

For plane's radial tyre H40×14.5-19 of Boeing B737 series aircraft,9 different structural layers of the tire are established in ANSYS such as tread,ply,the tyre shoulder,etc. The tyre pressuring progresses of different shape disks are simulated when considering the three non-linearity of tyre (material non-linearity,the geometric nonlinearity and contact non-linearity)and the influence of tyre and rim爷s adhesion due to long-term use by the pilot node method. The result shows that the tyre decomposition is best when βequals to 40°. The model can provide a theoretical basis to structures'design of plane tyre dismounting machine and the further optimization of disk.

Key words: plane tyre, finite element, ANSYS, tyre dismounting machine, contact analysis
