    摘要:

    为了改善挖掘机铲斗关节摩擦副的磨损问题,以特定的挖掘机模型为例,通过模拟挖掘机铲斗关节摩擦副的典型工况确定其相应的载荷,采用有限元法对此加载条件下各种形貌微织构表面的应力分布进行了研究。采用GY-LC-01型飞秒激光打标机对1Cr13基体表面加工一定尺寸的微织构,在有油润滑条件下,使用端面摩擦磨损试验机进行摩擦磨损试验,利用三维扫描深度显微镜观察磨损表面,研究了不同微织构的摩擦机理以及润滑条件下摩擦副的减摩效果。研究结果表明,织构表面的摩擦性能优于非织构表面,应力集中在织构边缘,圆形织构表面应力最小、减摩耐磨特性最好,具有最低的平均摩擦因数。

    Abstract:

    In order to solve the wear problem of the bucket joint friction vice of the excavator, a specific excavator model is taken as an example to determine the corresponding load by simulating the typical working conditions of the excavator bucket joint friction pair, with the finite element method adopted to study the stress distribution of various micro textured surfaces under this loading condition. The GY-LC-01 femtosecond laser marking machine is used to process certain size of microstructures on the surface of 1Cr13 substrate, with the friction and wear tests conducted by using end face friction and wear testing machine under oil lubrication condition. The worn surfaces is observed by using a three-dimensional scanning depth microscope to study the friction mechanism of different microstructures and the anti-friction effect of friction pairs under lubrication condition. The results show that the textured surface is characterized with a better friction performance, with stress concentrated at the edges of the texture. Circular textured surfaces are characterized with the lowest stress and the best anti-friction and wear-resistant properties, with the lowest average friction coefficient.
