一种子午线轮胎胎面花纹结构的设计方法
技术领域
本发明涉及轮胎设计领域，尤其涉及一种子午线轮胎胎面花纹结构的设计方法。
背景技术
胎面花纹不仅是轮胎外观的重要组成部分，而且是轮胎的直接接地部位。因此，轮胎胎面花纹不仅决定了轮胎是否美观，更影响着轮胎能否发挥牵引、制动、排水、转向、噪音、节油等重要功能。轮胎胎面花纹主要包括花纹块、花纹沟和花纹节距。此外，为了提升轮胎在湿滑路面或冰雪路面的操作性能，会在轮胎胎面中设计刀槽花纹，是一种既经济又实用的提高轮胎制动性能、延长轮胎寿命的方法。前人已经提出了各种刀槽花纹设计以满足不同的使用情况。如CN100548723C提供了一种具有高横向刚度的刀槽花纹型轮胎胎面以改善刀槽花纹型轮胎的干燥路面操作性能，CN105835267提供了一种用于轮胎花纹的3D立体钢片以提高轮胎对湿滑地面的抗滑性及转弯性能。事实上，适当降低轮胎刚性可以增加轮胎接地面积，从而提高轮胎的操纵稳定性、舒适性和行驶里程。轮胎刚性包括横向刚性、纵向刚性、径向刚性、扭转刚性和包络刚性。刀槽的加入会打断原花纹块的连续性，使得花纹块在横向(侧向)、纵向(轮胎行驶方向)和扭转(转弯)等各个方向上的受力更加均匀。因此，刀槽花纹主要对轮胎横向刚性、纵向刚性和扭转刚性有影响，而对径向刚性和包络刚性影响较小。但是，目前尚无一种降低轮胎刚性的刀槽型花纹设计方法。
发明内容
为了解决上述的技术问题，本发明的目的是提供一种子午线轮胎胎面花纹结构的设计方法，该方法通过确定刀槽花纹深度和轮胎刚性的关系，提高花纹设计效率，降低轮胎开发成本。
为了实现上述的目的，本发明采用了以下的技术方案：
一种子午线轮胎胎面花纹结构的设计方法，该方法通过刀槽花纹沟槽深度调节轮胎横向刚性、纵向刚性和扭转刚性大小，所述的刀槽花纹是窄而深的细长花纹，相对轮胎主花纹，刀槽花纹宽度为1～2mm，深度不超过主花纹深；
横向刚性下降率和刀槽花纹深的关系：
D1＝(23.12h/hw+8.81)/100；
纵向刚性下降率和刀槽花纹深的关系：
D2＝(34.37h/hw+5.98)/100；
扭转刚性下降率和刀槽花纹深的关系：
D3＝(10.73h/hw+15.34)/100
h为刀槽深度，hw花纹深度。
本发明的刀槽花纹可以降低轮胎的刚性，增加轮胎接地面积，从而提高轮胎的操纵稳定性、舒适性和行驶里程。通过沟槽深度可以调节轮胎横向刚性、纵向刚性和扭转刚性大小。通过本发明确定的刀槽花纹深度和轮胎刚性的关系，合理设计刀槽花纹深度，有助于提高花纹设计效率，降低轮胎开发成本。
附图说明
图1是本发明胎面实例的示意图；
图2是图1中A-A剖视示意图；
图3是轮胎刚性下降率和刀槽花纹深度的关系曲线。
具体实施方式
图1是一种典型的刀槽型胎面花纹，1为主花纹沟，2为刀槽花纹、3为花纹块，刀槽花纹宽度为1～2mm。图2为图1在A-A剖面的示意图，阴影部分为刀槽花纹剖面，刀槽花纹深度可调，且其深度不超过主花纹深。
在本实例中，通过加入不同深度的刀槽花纹，测试对应轮胎刚性值并与无刀槽花纹轮胎对比。刚性值下降率和刀槽花纹深度关系见图3，其中：
