摘　　要：建立了8种鞋底花纹的几何模型,使用ABAQUS联合FLUENT软件对橡胶鞋底的止滑性能进行了模拟研究。以流体压力和鞋底接地面积两个参数为评价标准,对不同橡胶鞋底花纹的止滑性能进行了数值预测。流体压力仿真结果表明,边长为6 mm的斜45°正方形花纹的流体压力最大值最低,排水能力最好,止滑性能最好;然后,在流体压力最大值最低的斜正方形花纹的基础上,通过改变橡胶的硬度,来改变接地面积。模拟结果表明,随着橡胶硬度的降低,鞋跟接地面积增大,但鞋后跟在邵尔A硬度约为62以下,接地面积趋于不变,在该硬度下,即可获得好的止滑性能。In this investigation,the geometric models of eight different shoe sole patterns were established and the slip resistance performance of rubber shoe soles was numerically investigated by using of ABAQUS and FLUENT software.The slip resistance performance of various rubber sole patterns were simulated and predicted using two parameters,fluid pressure and contact area,as evaluation criteria.The simulation results showed that the square pattern with oblique 45°and a side length of 6 mm exhibited the lowest maximum fluid pressure,demonstrating the best drainage capability,and the best slip resistance performance.Moreover,the contact area was varied by changing the hardness of the rubber on the basis of a diagonal square pattern with the lowest maximum fluid pressure.The numerical results show that the contact area of heel increases as the hardness of the rubber decreases.However,when the hardness reaches approximately below shore A 62,the contact area remains virtually unchanged.It is within this hardness range that the optimal slip resistance performance may be achieved.
