| 中文摘要: |
| 利用有限元分析软件研究195/85R16LT轮胎的行驶面弧度高（h）对成品性能的影响。结果表明：随着h减小，轮胎胎肩部位花纹块的接地压力逐渐增大、胎冠中心部位花纹块的接地压力逐渐减小，胎肩和胎圈部位的受力分布也发生变化；方案1轮胎（h＝6.5 mm）的接地因数和平均接地压力最大，接地压力分布不均匀，抓着性能和操控性能较好，滚动阻力较高，耐磨性能差；方案3轮胎（h＝5.5 mm）接地印痕的矩形率接近1，接地印痕形状为矩形，接地压力偏度值最小，平均接地压力也较小，耐磨性能好；方案2轮胎（h＝6 mm）的2#带束层端点应变能密度、胎体帘布反包端点应变能密度和加强层反包端点应变能密度最小，耐久性能最好。 |
| 英文摘要: |
| The influence of arc height of running surface（h） on the performance of 195/85R16LT tire was studied by using finite element analysis software.The results showed that，with the decrease of h，the grounding pressure of the pattern block on the shoulder of the tire increased gradually，the grounding pressure of the pattern block on the center of the crown decreased gradually，and the force distribution on the shoulder and the bead also changed.Scheme 1 tire（h=6.5 mm） had the highest grounding factor and average grounding pressure，uneven grounding pressure distribution，better grip and handling performance，higher rolling resistance and poor wear resistance.The rectangular ratio of scheme 3 tire footprint（h=5.5 mm） was close to 1，the footprint was rectangular，minimum skewness value of grounding pressure，lower average grounding pressure and good wear resistance.Scheme 2 tire（h=6 mm） had the best durability with the minimum strain energy density at the end of 2# belt，the turn-up end of carcass cord，and the turn-up end of reinforcing layer. |
