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
