| 中文摘要: |
| 在充分考虑轮胎结构本身特点和弹性体之间接触的情况下，提出了轮胎/地面接触的半解析解形式，计算了轮胎在不同载荷下的接地长度和最大下沉量，并由此提出轮胎径向静刚度的计算公式:K = R2 - a22 a5 W5 a。经验证明，计算出的接地长度与接地长度实验值吻合很好。 |
| 英文摘要: |
| A semi-analytic solution of tire/ ground contact was proposed by considering the inherent characteristic of tire st ructure and the contact between elastomers. The ground contact lengthes and the maximum deflections of tire with different loads were calculated and an equation
for the static radial stiffness of tire was derived :K = R2 - a22 a5 W5 a.It was shown that the calculated static radial stiffness of tire was well fit to that from experiment . |
