摘　　要：介绍24.00R35全钢工程机械子午线轮胎的设计。结构设计:轮胎外直径2 181 mm,断面宽646 mm,行驶面宽度558 mm,行驶面弧高32.88 mm,胎圈着合直径884 mm,断面水平轴位置(H_1/H_2)0.87;胎面花纹采用等节距设计,花纹深度65 mm,花纹饱和度65.8%。使用Solidworks软件对轮胎进行三维设计,通过有限元分析优化轮胎轮廓和材料分布。施工设计:胎面施工采用挤出胶条热缠绕方式,带束层为4层带束层结构,其中1~#—3~#带束层采用7×7×0.22+0.15HT钢丝帘线,4~#带束层采用高伸长的3×4×0.20HE钢丝帘线,胎体采用7×7×0.22+0.15HT钢丝帘线,钢丝圈采用Φ2.0 mm高强度钢丝。成品轮胎试验结果表明,轮胎外缘尺寸和耐久性能达到国家标准和设计要求。The design on 24. 00R35 all steel off-the-road radial tire was described.In the structure design,the following parameters were taken：overall diameter 2 181 mm,cross-sectional width 646 mm,width of running surface 558 mm,arc height of running surface 32. 88 mm,bead diameter at rim seat 884 mm,and maximum width position of cross-section（H1/H2） 0. 87.The tread pattern was designed with equal pitch,pattern depth was 65 mm,and bolck/total ratio was 65. 8%.Three-dimension design was used with Solidworks software,and tire profile and material distribution were optimized by finite element analysis.In the construction design,the following processes were taken：hot winding extrusion strip for tread,four layers belt,7×7×0. 22＋0. 15 HT steel cord for 1~#—3~# belt,3×4×0. 20 HE steel cord for 4^# belt,7×7×0. 22＋0. 15 HT steel cord for carcass,and Φ2. 0 mm steel cord for bead wire.It was confirmed by the finished tire test that,the inflated peripheral dimension and endurance performance reached the requirements of national standards and the design.
