摘　　要：自润滑关节轴承是依靠内外圈间的固体润滑材料实现润滑的一类关节轴承,其最主要的失效形式为磨损失效,对其磨损寿命的研究方法可分为基于计算机的数值计算和基于试验机的直接测试两大类。首先综述了目前应用最多的3种自润滑关节轴承寿命预测数值计算方法,包括有限元分析法、分子动力学法、人工神经网络方法,重点介绍了这几种方法的原理、主要研究方法和目前的研究现状。然后,总结了试验测试方法的主要研究内容,关节轴承磨损寿命试验机的研发是进行试验测试的前提,自润滑关节轴承磨损寿命分布规律是试验研究的主要内容,加速寿命试验是自润滑关节轴承试验最常用的手段。由此,分别从自润滑关节轴承磨损寿命试验机研发、自润滑关节轴承磨损寿命试验、加速试验在自润滑关节轴承试验研究中的应用等3个方面,探究了自润滑关节轴承磨损寿命直接试验方法的研究现状。最后展望了自润滑关节轴承磨损寿命研究的发展趋势。Self-lubricating spherical plain bearing is a kind of spherical plain bearing that relies on solid lubricating material between inner and outer rings to realize lubrication.Because of its advantages of small volume,light weight,maintenance-free and high reliability,self-lubricating spherical plain bearing has gradually replaced traditional oil and grease lubricated bearings in some special working conditions.In actual service,wear failure is the main cause of failure of self-lubricating spherical plain bearing.Exploring the evolution law of wear life of self-lubricating spherical plain bearing is an important measure to ensure the safety of equipment in service.Therefore,the work aims to introduce the development status of research methods on wear life of self-lubricating spherical plain bearing.The research methods of wear life of self-lubricating spherical plain bearing were summarized into two categories:numerical calculation based on computer and direct test based on testing machine.Firstly,three kinds of numerical calculation methods for life prediction of self-lubricating spherical plain bearing,including finite element analysis method,molecular dynamics method and artificial neural network method,were summarized.Finite element analysis method was used to study the wear life problems of self-lubricating spherical plain bearing,which was one of the most commonly used computer numerical calculation methods.The finite element software could not only analyze the effect of bearing molding process of wear life,but also investigate the load distribution of friction contact surface,the temperature distribution and displacement variation of numerical calculation when combined with the corresponding theory of wear and tear.Then,the wear life of self-lubricating spherical plain bearing was obtained.Molecular dynamics method was an indirect method to evaluate the performance of self-lubricating spherical plain bearing,which was mainly applied to the simulation calculation of the friction and wear performance of the sel
