摘　　要：为研究纳米水基SiC流体的润滑性,采用表观油膜厚度法对其进行润滑性分析。首先,采用两步法制备出稳定的纳米水基SiC流体,然后,利用表观油膜厚度法将纳米水基SiC与2种新型环保液压介质—淡水和海水进行润滑性分析对比,最后,运用AMEsim软件对表观油膜厚度法的分析结果进行验证。通过建立液压仿真系统,应用以上3种流体作为介质进行系统仿真实验,得出液压缸内3种介质的泄漏量曲线。实验结果表明,纳米水基SiC流体的润滑性优于淡水和海水的润滑性。In order to study the lubricity of nano-water-based SiC fluids,oiliness analysis was carried out using apparent oil film thickness method.Firstly,a stable nano-water-based SiC fluid was prepared by a two-step method.Then,the apparent oil film thickness method was used to compare the lubricity of nano-water-based SiC with two new environmentally friendly hydraulic media,fresh water and seawater.Finally,the AMEsim software was used to compare the table.The analysis results of the oil film thickness method were verified.Through establishing the hydraulic simulation system,the above three fluids were used as the medium for the system simulation experiment,and the leakage curves of the three media in the hydraulic cylinder were obtained.The experimental results show that the lubricity of nano-water-based SiC fluid is better than that of fresh water and seawater.
