基于ABAQUS的34×10.75-16航空轮胎非线性有限元分析

摘要

基于轮胎变形的几何非线性、轮胎与地面接触的非线性、轮胎材料的非均匀性及橡胶基复合材料的各向异性的特性，通过AutoCAD软件设计轮胎断面的轮廓结构，利用ABAQUS有限元软件建立34×10.75-16航空轮胎结构有限元模型。通过ABAQUS/ATNDARD求解器仿真计算，得到不同充气压力工况下相应的载荷与变形量。根据仿真结果与轮胎测试结果对比分析表明，建立的有限元分析模型能够模拟该型号航空轮胎各工况条件下的力学行为，为轮胎设计提供参考。%In considering of geometric nonlinearity of tire deformation, nonlinear of tire contact with the ground, inhomogeneity of tire material and anisotropy of rubber matrix composites, outline structure of tire cross-section was designed by software AutoCAD and 34×10.75-16 aircraft tire structure finite element model was established via ABAQUS. The corresponding load and deformation under different inflation pressure was attained after the simulation calculation of ABAQUS/ATNDARD. The simulation results were compared with experimental values. The results showed that the established finite element model could simulate the mechanical behaviors of this type of aircraft tire which provides a reference for tire performance design.
