| 中文摘要: |
| 介绍15.5/60-18 8PR低断面无内胎工程机械轮胎设计。结构设计：轮胎外直径927 mm，断面宽度398 mm，行驶面宽度360 mm，行驶面弧度高22.5 mm，胎圈着合直径459 mm，胎圈着和宽度330 mm，断面水平轴位置0.814，花纹深度18 mm，花块饱和度 43.7%。施工设计：胎体采用4层高强度1400dtex/2锦纶6帘布，成型采用半芯轮式机头。成品轮胎的外缘尺寸符合设计要求，物理性能达到国家标准要求。 |
| 英文摘要: |
| The design of 15.5/60-18 8PR low profile tubeless OTR tire is introduced in this paper. In the structure design， the parameters are as follows： tire overall diameter 927 mm， cross sectional width 398 mm， width of running surface 360 mm， arc height of running surface 22.5 mm， bead diameter at rim seat 459 mm， bead width at rim seat 330 mm， maximum width position of cross section 0.814， pattern depth 18 mm， and pattern block ratio 43.7%. In the construction design， a 4-layer high strength 1400dtex/2 nylon 6 cord is applied for carcass ply， and a semi-core building drum is used to build tires. The experimental test results on the finished tire showed that the inflated peripheral dimension meets the design target， and the physical properties meet the requirements of national standards. |
