摘　　要：采用TYABAS系列分析软件和ABAQUS软件,建立了380/85R24农业子午线轮胎的仿真模型,研究轮胎花纹对接地印痕和接地压力等接地特性的影响规律。通过有限元分析及实测结果表明:与14.9-248PR农业斜交轮胎相比,380/85R24农业子午线轮胎的接地印痕呈矩形,胎冠部位的接地面积增大,平均接地压力减小,接地压力分布相对均匀,耐磨性能提高,轮胎使用寿命延长。Using TYABAS series analysis software and ABAQUS software,simulation model of 380/85R24 agricultural radial tire was established to study the influence of tread pattern on the grounding characteristics of the tire,such as grounding imprints and grounding pressure.The finite element analysis and experimental test results showed that,compared with 14.9-248PR agricultural bias tires,the grounding imprints of 380/85R24 agricultural radial tires were rectangular,the grounding area at the tire crown increased,the average grounding pressure decreased,the grounding pressure distribution was relatively uniform,the wear resistance was improved and the service life of the tire was extended.
