摘要

提出了一种优化的柔性环轮胎有限元建模方法,该方法在传统的径向弹簧支撑的柔性环模型上优化了弹簧的数量并采用B21线性梁单元等效胎体的变形。该研究应用万能试验机对哑铃型轮胎橡胶片进行单轴拉伸试验,得到了应力-应变曲线,采用有限元仿真软件Abaqus对材料拉伸数据进行了超弹性和黏弹性评估拟合,在自由状态及载荷状态下对普通子午线轮胎柔性环模型进行了线性摄动模态分析,并提取了振型与固有频率。通过与Singlemodle分析结果的对比,验证了此建模方法的有效性和准确性。该研究还应用该模型预测了在动力学条件下,速度、载荷、胎压对轮胎固有频率影响的规律,为轮胎结构分析和设计提供了参考。

Abstract

An optimized finite element modeling method for flexible ring tires was proposed. This method optimizes the number of springs on the conventional flexible ring model supported by radial springs and uses the equivalent carcass deformation of B21 linear beam elements. In this paper, a universal testing machine was used to perform a uniaxial tensile test on a dumbbell-shaped tire rubber sheet, and the stress-strain curve was obtained. The finite element simulation software Abaqus was used to perform superelastic and viscoelastic evaluation and fitting on the material tensile data. A linear perturbation modal analysis was performed on the flexible ring model of a normal radial tire under load and load conditions, and the mode shapes and natural frequencies were extracted. Compared with Singlemodle analysis results, the validity and accuracy of this modeling method was verified. The model was also used to predict the law of the effects of speed, load, and tire pressure on the tire’s natural frequency under dynamic conditions, which provides a reference for tire structure analysis and design.
