摘　　要：研究胎圈着合宽度对7.00R16LT全钢轻型载重子午线轮胎性能的影响。结果表明,与胎圈着合宽度采用标准轮辋宽度设计轮胎相比,着合宽度宽半寸设计轮胎在标准轮辋上装配后胎圈部位内收位移增大,胎圈部位与胎肩部位的应力分布得到平衡,胎肩部位接地压力分布得到较大改善,轮胎耐久性能提升了8%。The effect of bead width at rim seat on the performance of 7.00R16LT all-steel light truck and bus radial tire was studied.The results showed that,compared with the tire designed with a standard rim width for the bead width at rim seat,tires designed with an extra half-inch bead seat width showed increased retraction displacement in the bead seat area after being assembled on standard rims,the stress distribution between the bead and the shoulder was balanced,the shoulder contact pressure distribution was greatly improved,and the tire durability was enhanced by 8%.
