| 中文摘要: |
| 利用Abaqus软件对295/80R22.5全钢载重子午线轮胎强度进行仿真分析。建立模型时普通型和高抗冲击型钢丝帘线分别采用线弹性和Marlow超弹性本构模型，并准确描述和输入钢丝帘线间距。结果表明：根据强度试验前半段钢丝帘线力的变化趋势，可预测后半段钢丝帘线力均为线性变化，结合钢丝帘线最小破断力，可得到轮胎强度试验的最大行程，并计算得到探头压力；轮胎强度仿真计算结果与试验结果误差满足工程要求，仿真计算可作为轮胎强度设计的验证手段之一。 |
| 英文摘要: |
| The strength of 295/80R22.5 truck and bus radial tire was simulated and analyzed by using Abaqus software.When establishing the model，the linear elastic and Marlow hyperelastic constitutive models were used for ordinary and high-impact steel cord respectively，and the steel cord spacing was accurately described and input.The results showed that，according to the change trend of the steel cord force in the first half of the strength test，it could be predicted that the steel cord force in the second half was linear.Combining with the minimum breaking force of the steel cord，the maximum stroke of the strength test could be obtained，and the probe pressure could be calculated.The error of the tire strength between the simulation calculation and test results met the engineering requirements，and the simulation calculation could be used as one of the verification means of tire strength design. |
