多孔储液自润滑介质结构源于生物关节软骨，可解决极端工况下润滑自补偿难题。但目前对其润滑状态及机理的分析还缺乏相应的理论基础，导致其在工业应用中存在工况适应性不确定问题，引发工程隐患。该问题是一涉及多孔介质、润滑液、结构变型及运动的复杂非线性固-液耦合问题，没有理论解可用。为此，本项目将固-液耦合数值模拟与实验相结合，建立多孔介质耦合支配方程，在数值模拟的基础上进行实验验证和优化。目标如下：1）建立多孔储液自润滑介质渗流及析出液在摩擦界面运动演化的动力学模型及相应的实验技术，提出润滑状态预测及工况适应性研究方法；2）获得影响其固-液相平衡承载与润滑状态转变的关键控制因素，揭示其储液自循环成膜及润滑机理；3）获得其物理结构、材料参数、工况条件与润滑状态间的关系，形成环境自适应性多孔储液自润滑介质设计方法。预期成果可为环境自适应性多孔储液自润滑摩擦副的功能可控性设计和应用提供理论指导和技术支持。

The structure of self-lubricating porous reservoir medium is derived from biological articular cartilage, which can solve the problem of self-compensating lubrication under extreme working conditions. However, there is still a lack of theoretical basis for describing its lubrication regime, which leads to uncertainty of working conditions adaptability in industrial applications and engineering hidden dangers. The problem involves complex nonlinear structure- fluid interaction among porous media, lubricating fluid, structural variation and motion, without theory solution. Therefore, this project try to combine structure-fluid interaction numerical simulation with experiment technology to establish the governing equation of porous media and then conduct experimental verification and optimization. The target is as follows: 1) Establish the dynamic analysis and numerical simulation model of seepage and precipitate evolution of porous reservoir media and corresponding experimental technology, and propose the lubrication regime prediction and condition adaptability research method; 2) Obtain the key control factors affecting the solid-liquid phase equilibrium loading and lubrication regime transition, and reveal the generation of self-circulation lubrication film and its lubrication mechanism;3) Obtain the relationship between its physical structure, material parameters, working conditions and lubrication regime, and form an environmental self-adaptive porous reservoir self-lubricating medium design method. The expected results will provide theoretical guidance and technical support for the design and application of functional controllability of self-lubricating friction pair of environmental adaptive porous reservoir, which has important theoretical significance and engineering value.
