摘　　要：采用形变控制设计方法(Deformation Control Method,DCM)设计全钢巨型工程机械子午线轮胎轮廓,利用有限元技术进行分析优化,并研制出成品轮胎与国外品牌轮胎进行对比试验。全钢巨型工程机械子午线轮胎具有高负荷、瞬间受力大、路面使用条件苛刻等特点,设计上应控制充气时轮廓、带束层端点应力以及胎圈区域的应力应变。有限元分析结果表明,不同负荷下轮胎轮廓变化与DCM设想一致,且轮胎最大应力位置始终在肩部带束层端点附近。轮廓测量结果表明,在标准充气压力下,随着负荷率的增大,DCM成品轮胎的轮廓变化趋势与国外品牌轮胎一致,但国外品牌轮胎的胎面变形更小,断面水平轴下移更小、大负荷下胎侧横向变形率较大。实际应用情况表明,DCM成品轮胎的使用寿命达到预期国际品牌轮胎的70%左右。The profile of all steel giant off-the-road radial tire was designed by using the deforma-tion control method （DCM） and optimized by finite element analysis （FEA）. The finished tire was tested comparing with an international brand tire. Based on the characteristics of high load,large in- stantaneous stress and very harsh road conditions, the tire profile in inflating state, stress at the belt end,and the stress and strain of the tire bead should be controlled in the design. The FEA results showed that, under different load, the trend of profile change was consistent with the DCM design, and the maximal stress position was always around the belt end in tire shoulder. The measurement results showed that, under the standard inflation pressure, with the increase of loading rate, the trend of pro- file change of DCM finished tire was similar to that of the international brand tire, but the international brand tire had smaller tread deformation, less drop of the horizontal axis position, and bigger lateral deformation rate of sidewall under large load. The application test results showed that the life of DCM finished tire reached about 70% of the international brand tire.
