中文摘要: |
汽车行驶过程中轮胎各部位受力状态随着整车载荷转换而变化。作为子午线轮胎关键受力部件的带束层,其在受拉和受压时呈现出不同的变形状态与力学性能。基于拉压不同模量弹性理论,通过编写UPFs(User Programmable Features)材料子程序,对ANSYS软件进行二次开发,将带束层材料设置为不同的拉伸弹性模量与压缩弹性模量,模拟子午线轮胎充气和越障滚动工况。结果表明,考虑轮胎骨架材料在拉伸与压缩时的不同力学特性,更符合轮胎实际结构特征。该方法对准确仿真轮胎受力状态及轮胎结构设计优化有一定的参考价值。 |

In the process of vehicle driving,the stress state of each part of the tire changed with the load conversion of the whole vehicle.As the key component of radial tire,the belt showed different deformation and mechanical properties under tension and compression.Based on the elastic theory of different modulus in tension and compression,the material subprogram of UPFs(User Programmable Features) was compiled,and the secondary development of ANSYS software was carried out.The belt material was set to different tensile modulus and compressive modulus to simulate the inflation and obstacle crossing rolling conditions of radial tire.The results showed that considering the different mechanical properties of tire skeleton material in tension and compression,it was more consistent with the actual structural characteristics of tire.This method had a certain reference value to accurately simulate the tire stress state and tire structure design optimization. |
