摘　　要：防滑耐磨涂层作为一种功能涂层,已广泛应用于地面以提高防滑性能,但也存在抗污性差、使用舒适度低的问题。而球状凸起微结构的涂层表面可以通过增加实际接触面积,形成复杂的微观结构拓扑,以显著提高涂层的防滑性能、耐磨性能和防污性能。本研究基于ABAQUS仿真平台,建立了涂层凸起微结构与地板橡胶的接触模型。通过设计四类不同工况,分析了涂层厚度、表面结构、材料属性等参数对摩擦力的影响规律。结果表明:厚度为0.06 mm、表面具有0.12 mm直径、0.12 mm间距的半球凸起、采用材料3的涂层方案,可以实现摩擦力和涂层可靠性的最佳平衡。本研究区别于传统实验,通过仿真优化方法,分别对四个工况进行逐一分析,系统地研究了涂层设计与摩擦力的关系,得到了既能获得最大摩擦力,又考虑涂层可靠性的设计参数组合,为防滑耐磨涂料的制备以及其性能的提升提供了理论指导。Anti slip and wear-resistant coatings,as a functional coating,are widely used on the ground to improve anti slip performance,but there are also problems with poor anti fouling and low comfort of use.By increasing the actual contact area,the coating surface with spherical convex microstructure can form a complex microstructure topology,which can significantly improve the anti-slip,wear and anti-fouling properties of the coating.This study is based on the ABAQUS simulation platform and establishes a contact model between coatings and rubber.By designing four different working conditions,the influence of parameters such as coating thickness,surface structure,and material properties on friction force was analyzed.The results show that a coating scheme with a thickness of 0.06 mm,a hemispherical protrusion with a diameter of 0.12 mm and a spacing of 0.12 mm on the surface,and the use of material 3 can achieve the best balance between friction and coating reliability.This study is different from traditional experiments.Through simulation optimization methods,four working conditions were analyzed one by one,and the relationship between coating design and friction was systematically studied.A design parameter combination that can achieve maximum friction while considering coating reliability was obtained.It provides theoretical guidance for the preparation of anti slip and wear resistant coatings and their higher performance.
