| 中文摘要: |
| 基于超弹理论和橡胶试验数据，用3～5阶Ogden超弹模型分别对金属-橡胶复合锥形弹簧(以下简称锥形簧)的垂直刚度和强度进行模拟分析。结果表明，3阶和5阶Ogden模型的刚度分析结果在一定负荷范围内与试验值较吻合，在其它情况下存在较大偏差，而4阶模型在其负荷范围内与试验值吻合最好，刚度曲线呈现弱非线性。模型参数对锥形簧强度分析的影响比对刚度的影响小，但影响趋势一致。 |
| 英文摘要: |
| The 3rd，4th and 5th order hyperelastic Ogden models were used to analyze the vertical stiffness and strength of conical spring respectively，based on the hyperelastic theory and rubber experimental data.Comparison of the stiffness curves of simulation and test showed that，the fitted stiffness curves of the 3rd and 5th order Ogden models accorded with the test data in a certain range of load，and there was high deviation in other range of load.The fitted stiffness curve of the 4th order Ogden model agreed very well with the test data within the entire range of load.The stiffness curves behaved weakly non-linear.The effect of Ogden model parameters on the strength analysis was lower，but the relative trend of the effect on stiffness and strength analysis was consistent. |
