| 中文摘要: |
| 提出一种研究履带车辆轮胎在不同路况下动力学特性的仿真方法。首先建立轮胎精细有限元模型，然后在充分考虑轮胎的几何非线性、材料非线性和接触非线性的基础上模拟垂直负荷作用下轮胎与路面的接触过程，分析轮胎驶过不同路况时的力学特性和变形。结果表明，所提出的方法能有效准确地模拟履带车辆轮胎驶过不同路况的动力学
特性。 |
| 英文摘要: |
| A simulation method for studying the dynamic characteristics of tracked vehicle tire under different road conditions was proposed.Firstly，a detailed tire finite element model was established，and then on the basis of fully considering the geometric nonlinearity，material nonlinearity and contact nonlinearity of the tire，the contact process between the tire and the road under vertical load was simulated，and the mechanical characteristics and deformation of the tire when driving through different road conditions were analyzed.The results showed that the proposed method could effectively and accurately simulate the dynamic characteristics of tracked vehicle tire passing through different road conditions. |
