三角平衡轮廓轮胎振动模态的有限元分析

利用Abaqus有限元分析软件，建立三角平衡轮廓轮胎和传统轮廓轮胎的三维有限元模型，研究三角平衡轮廓轮胎的同有频率和振型，对比三角平衡轮廓轮胎与传统轮廓轮胎在轮辋和地面约束条件下的动态特性。结果表明，相比传统轮廓轮胎，三角平衡轮廓轮胎的同有频率较高，具有低滚动阻力优势。;Based on Abaqus software，the 3D finite element models of the triangle balanced profile tire and the traditional profile tire were established. The inherent frequency and vibration model of the triangle balanced profile tire were studied，and the dynamic characteristics of both types of tires with rim constraint and road constraint were compared. The results showed that， compared with the tradi tional profile tire， the inherent frequency of the triangle balanced profile tire was higher， and therolling resistance was lower
