摘要

为了探究子午线轮胎面内振动特性，本文建立了旋转超弹性厚壁REF模型。并在具有随动坐标系的绝对节点坐标法(absolute nodal coordinate formulation，ANCF)框架下，提出了平面内旋转环扇单元，对旋转超弹性厚壁REF模型进行离散。考虑到非线性本构关系和旋转运动中的广义惯性力，建立了该模型的非线性运动微分方程以及线性化运动微分方程。通过与现有文献中的实验结果进行对比，验证了上述模型的有效性，并分析了弹性基参数、环体厚度和旋转角速度对子午线轮胎固有特性的影响规律。

Abstract

In order to investigate the in-plane vibration characteristics of radial tire, a rotating hyperelastic thick wall ring on the elastic foundation (REF) model is established in this paper. In the framework of the absolute nodal coordinate formulation（ANCF) with comoving coordinate system, an in-plane rotating ANCF annular-sector element is proposed to discretize the rotating hyperelastic thick wall REF model. Considering the nonlinear constitutive relation and the generalized inertial force in rotating motion, the nonlinear differential equation of motion and linearized equation of this model are established. By comparing with the experimental results in the existing literature, the validity of the above model is verified, and the influence of elastic base parameters, ring thickness and rotation angular velocity on the vibration frequency of radial tire is analyzed.
