| 中文摘要: |
| 通过有限元仿真研究设计参数对全钢子午线轮胎胎圈耐久性能的影响。研究的设计参数包括胎圈包布内端点高度、角度和密度，三角胶模量、高度和下三角胶厚度，胎体和胎圈包布反包高度，胎圈内轮廓，胎圈水平轴高度，胎圈模具轮廓，胎圈着合宽度，钢丝圈排列和直径。通过建立不同设计参数与仿真判据（应变能密度）的响应关系，得到设计参数对胎圈耐久性能的影响趋势。 |
| 英文摘要: |
| The effect of design parameters on the bead durability of all-steel radial tire was investigated by finite element simulation.The design parameters studied in this paper included the endpoint height，angle and density of bead wrap，the modulus and height of apex，the thickness of lower apex，the turn-up height of carcass and bead wrap，the inner outline of bead，the horizontal axis height of bead，the mold outline of bead，the bead width at rim seat，the bead wire arrangement and diameter.By establishing the response relationship between design parameters with different values and simulation criteria（strain energy density），the effect trend of design parameters on the bead durability was obtained. |
